The spreadsheet glows at me like an accusation.

I'm sitting cross-legged on my bed at 2:47 AM, laptop balanced on my knees, my biometric data arrayed across the screen in columns of numbers that suddenly feel like they're written in a language I don't speak. My heart rate monitor data. My cortisol levels. The oxytocin measurements from the saliva samples I've been meticulously collecting for the past six weeks.

The data doesn't lie.

That's what I've built my entire life philosophy on. Data is honest. Numbers don't have agendas, don't manipulate, don't leave you bleeding on the kitchen floor while your mother screams that it's somehow your fault. Data is pure. Data is safe.

Data, apparently, is also a fucking traitor.

I cross-reference the spreadsheet again, running the same analysis I've already run four times. My fingers move mechanically across the keyboard, pulling up the graphs, the trend lines, the statistical significance markers. The coffee I made at midnight has gone cold and bitter beside me. Sophie's gentle snores drift through the thin wall that separates our bedrooms, and the radiator clanks and hisses like it's dying a slow, agonizing death.

The results don't change, no matter how many times I look at them.

When Marcus is present: my cortisol drops 23%. Not gradually, not over the course of hours—it drops within minutes of his proximity. Cortisol is the stress hormone. It's what floods your system when you're in danger, when you need to fight or flee. Lower cortisol means safety. Means trust.

My hypothesis predicted the opposite. Marcus was supposed to trigger a stress response—the initial alertness and arousal that comes with attraction, the chemical rush of novelty and danger. But that's not what the data shows. The data shows that my body treats Marcus like a safe harbor.

My body is an idiot.

The oxytocin levels are worse. The bonding hormone, the neurochemical basis of attachment, is elevated whenever I'm around him. Elevated when he touches me. Astronomical when he looks at me with those gray-green eyes like I'm the only person in the world he wants to understand. The pattern isn't the spike-and-crash of addiction—it's the steady, climbing elevation of genuine attachment.

Genuine.

I laugh, a brittle sound that cracks in the silence of my room. It sounds unhinged, which is probably accurate. I am losing my mind. This is what losing your mind sounds like at 2:47 AM when you realize that your entire carefully constructed thesis—the thing that's supposed to prove love is just chemicals and conditioning—has been contaminated by the most basic experimental error.

The researcher became the subject.

Worse: the researcher fell for the subject.

I slap the laptop shut, as if that will make the data disappear. It doesn't. The numbers are still there, burned into my retinas, impossible to unsee.

My phone buzzes on the nightstand. A text from Marcus, timestamped forty-five minutes ago: Can't sleep. Thinking about you.

I don't respond. I can't. Because if I do, I'll have to acknowledge that the tremor in my chest right now isn't caffeine-related anxiety—it's something far more dangerous.

Sophie finds me at 6:30 AM in the kitchen, staring into the refrigerator like it might contain answers along with the expired yogurt and half-empty bottles of craft beer.

"You look like you died," she announces, padding in wearing the oversized Columbia hoodie she stole from her ex-boyfriend and never returned. Her curls are a beautiful disaster on top of her head, and she smells like the vanilla lotion she's been using since sophomore year. "Did you sleep at all?"

"No."

"Want to talk about it?"

"No."

Sophie pours herself coffee with the efficiency of someone used to my refusals. She leans against the counter, regarding me with those warm brown eyes that somehow see straight through every defense I've ever constructed. It's deeply unfair.

"This is about Marcus," she says. Not a question.

"It's about my thesis."

"Your thesis is about Marcus."

"My thesis is about the neurochemistry of romantic attachment and the extent to which it can be manipulated through conditioning and environmental factors."

Sophie takes a slow sip of coffee. "Right. And how's that going? Is it proving that love is just chemicals and manipulation?"

I don't answer. I can't answer without my voice cracking, and I will not give Sophie the satisfaction of watching me crack before 7 AM.

She sets down her mug and moves closer, leaning against the refrigerator next to me. We stand in silence for a moment, a comfortable silence that's been earned through three years of late-night conversations and shared trauma and the kind of friendship that survives even when you're actively trying to destroy it.

"Show me," Sophie says quietly.

"No."

"Iris."

"I said no."

"Show me the data."

I could refuse. I should refuse. Instead, I find myself walking to my bedroom and returning with my laptop, opening it to the spreadsheet that's been haunting me since 2:47 AM. Sophie takes it from me, her eyes scanning the numbers, and I watch her face shift from curiosity to understanding to something that looks uncomfortably like pity.

"Oh, honey," she whispers.

"Don't."

"Your cortisol—"

"I know what my cortisol levels say."

"And your oxytocin—"

"I'm aware of my oxytocin levels, Sophie. I collected the samples myself."

She looks up from the screen, and her expression is so gentle it actually makes my throat tight. "When did you realize?"

"I didn't realize anything. The data is contaminated."

"The data is telling you the truth."

"The data is telling me that my methodology is flawed and my control is compromised and I'm a terrible scientist who let personal feelings interfere with—"

"With what? With falling in love?"

The words hit like a slap. I feel my face flush, feel my hands clench into fists, feel the familiar spike of panic that comes when someone gets too close to the raw truth.

"I'm not in love with him," I say, and it sounds like a lie even to me. It sounds like the kind of lie I used to tell my therapist when I was sixteen and convinced that if I just pretended hard enough, the nightmares would stop.

Sophie closes the laptop. Sets it gently on the kitchen table. She reaches out and takes my hand, and I let her, because fighting her would require more energy than I have left.

"What if you were?" she asks softly. "What if the experiment didn't fail because of contamination—what if it succeeded? What if it proved that love isn't just chemicals and conditioning? What if it proved that sometimes, the chemicals and the conditioning are actually... real? Actual attachment?"

"That's not what—"

"What are you afraid of?"

The question hangs in the kitchen air like cigarette smoke. I can see the dust motes floating through the early morning light coming through the window. I can hear the radiator hissing. I can feel my heart rate accelerating, my cortisol spiking—the exact opposite of what happens when Marcus is near.

"I'm afraid," I say, and my voice sounds small and young and broken, "of becoming my mother."

Sophie squeezes my hand. She doesn't say anything. She just waits, the way she always does, while I fall apart in increments.

"She loved my father so much," I continue, the words tumbling out before I can stop them. "She loved him so much that when he left, she just... dissolved. She became this desperate, needy version of herself, calling him, begging him to come back, falling apart in front of me and my sister like we were supposed to fix it. Like we were supposed to make her whole again. And I promised myself I would never—I would never be like that. I would never let someone have that kind of power over me."

"Marcus isn't your father," Sophie says.

"I know that."

"And you're not your mother."

"I don't know that." The panic is rising now, a tide of it, flooding through my chest. "What if I am? What if this is just the beginning? What if I let myself love him and he leaves and I turn into some pathetic version of myself that can't function? What if—"

My breathing is getting shallow. I can feel it, the familiar tightness in my chest, the way the world starts to narrow and compress until there's only the panic and the certainty that I'm going to die right here in my kitchen on a Wednesday morning.

Sophie pulls me to the couch. She sits me down and puts her arm around me, and I let her, because I'm falling apart and there's no point in pretending otherwise.

"You're having a panic attack," she says, in that calm, steady voice she uses when I'm spiraling. "Your body is scared, but your body is lying to you. You're safe. You're here, you're with me, you're safe."

I focus on her voice. On the scent of her vanilla lotion. On the solid weight of her arm around my shoulders. Gradually, my breathing evens out. The tightness in my chest loosens, just slightly.

"What do I do?" I ask, and I hate how small I sound.

"You talk to him," Sophie says. "You tell him the truth."

"The truth is that I'm a disaster. The truth is that I'm terrified. The truth is that I built an entire experiment on the premise that love is just chemicals and I was wrong and—"

"The truth is that you're in love with him."

I don't deny it this time. I can't. The data is too clear, and I've spent my entire life worshipping at the altar of data. I can't start lying to myself now, not when it matters.

"What if he doesn't feel the same way?" The question comes out as barely a whisper.

"Then you deal with that," Sophie says. "But you'll deal with it as yourself, not as some diminished version of yourself that he controls. You're not your mother, Iris. You're stronger than that."

I want to believe her. I want to believe that I'm capable of loving someone without losing myself in the process. I want to believe that the data—my body's honest response to Marcus—means something other than disaster.

But mostly, I just want to keep breathing.

I don't text Marcus back until later that afternoon.

I've spent the intervening hours in the library, ostensibly working on my thesis but actually just staring at the same paragraph about neuroplasticity for three hours. I've changed my clothes three times. I've reapplied my deodorant twice because I'm paranoid that I smell like panic. I've done everything except actually deal with the fundamental problem, which is that I'm in love with Marcus Reid and I have no idea what to do about it.

Finally, at 4:17 PM, I pull up his contact and type: Can we talk?

His response comes within seconds: Always. My place? 6?

Always. Like it's not even a question. Like of course he'll make time for me. Like I'm not just another girl in a long line of girls.

I type back: Yes.

Then I sit with that simple affirmation for the next hour and forty-three minutes, feeling like I'm standing on the edge of a very high cliff, trying to decide whether to jump.

---

Marcus's apartment smells like him before I even step inside.

Cedarwood and smoke, that intoxicating blend that's become my personal drug of choice, mixed with something else—something like old paper and coffee. He opens the door before I can knock, and he's wearing a gray henley that clings to his chest in a way that's absolutely not helping my ability to think clearly.

"Hey," he says, and there's something vulnerable in his voice that I've never heard before. Something that suggests I'm not the only one who's been spiraling. "I wasn't sure you'd come."

"I wasn't sure either," I admit.

He steps aside, and I cross the threshold into his space. His apartment is exactly what I expected—expensive but lived-in, with books stacked on the floor and a record player in the corner and evidence that he actually exists in this space rather than just using it as a backdrop for seduction. There's a half-finished coffee on the side table. A hoodie draped over the back of the couch. Real things. Human things.

"Do you want to sit?" he asks, gesturing to the couch.

I don't sit. I stand in the middle of his living room, my hands shoved deep into the pockets of my jacket, trying to find the words I've been rehearsing all afternoon.

"I need to tell you something," I say. "And I need you to let me finish before you respond, because if you interrupt me, I will lose my nerve and walk out of here, and I don't think I can do this twice."

Marcus nods slowly. He doesn't move closer, which I appreciate. He just waits, those gray-green eyes fixed on me with an intensity that makes my skin feel too tight.

"My thesis is based on the premise that romantic attachment is just a combination of neurochemical responses," I continue, the words tumbling out in the same way they did with Sophie. "That love is oxytocin and dopamine and cortisol, and that these responses can be manipulated and conditioned. I built this entire experiment to prove that romantic attachment is predictable and controllable and ultimately, not real."

I pause, gathering my courage.

"I was wrong."

Marcus takes a breath like he wants to speak, but I hold up a hand and he stays silent.

"The data shows that my hypothesis was flawed. My own physiological responses to you don't match the pattern of conditioned attraction. My cortisol drops around you, which means my body perceives you as safe. My oxytocin is elevated, which means my body is bonding with you. My dopamine response doesn't match addiction—it matches genuine attachment. My own body is telling me that what I feel for you is real, and I spent the last twenty-four hours having an existential crisis about it because I built my entire identity on the belief that love is just chemicals and manipulation and I was wrong and I'm terrified."

I finally take a breath.

"I'm terrified," I repeat, "because loving you means being vulnerable, and being vulnerable means the possibility of being destroyed, and I watched my mother get destroyed by love and I swore I would never let that happen to me. But the data doesn't lie, Marcus. And the data is telling me that I'm in love with you, and I don't know how to reconcile that with everything I thought I believed."

The silence stretches between us like a living thing. Marcus hasn't moved. He's just standing there, watching me fall apart, and I can see the moment something shifts in his expression—something that looks like understanding.

"Can I talk now?" he asks quietly.

I nod.

He moves closer, slowly, giving me time to run if I want to. I don't run. I stand frozen as he reaches up and tucks a strand of hair behind my ear, his fingers lingering against my cheek. His touch is gentle, careful, like I'm something precious that might break.

"I've been lying to myself about you since the moment you walked into that coffee shop," he says. "I told myself this was a game. I told myself I could seduce you and move on like I always do. But then you started looking at me like I was an actual person instead of just a pretty face, and everything changed. You changed it."

His hand moves to my jaw, tilting my face up toward his. His scent surrounds me—cedarwood and smoke and something wild and dangerous.

"I'm terrified too," he continues. "I'm terrified that you're going to realize I'm not worth the vulnerability. I'm terrified that I'm going to hurt you the way my father hurt my mother. I'm terrified that I don't know how to love someone without destroying them. But I'm more terrified of not trying."

He leans down, and I think he's going to kiss me, but instead he just rests his forehead against mine, his breathing ragged and uneven.

"I love you," he whispers. "I know that's insane, and I know we've only known each other for six weeks, and I know your entire thesis is about how love is just chemicals and conditioning. But I don't care. The data can say whatever it wants—I know what I feel, and it's you. It's always been you."

My heart is racing. My hands are shaking. Every instinct I have is screaming at me to run, to protect myself, to retreat back into the safety of data and logic and emotional distance.

Instead, I reach up and kiss him.

It's not gentle. It's desperate and hungry and absolutely reckless. It tastes like cedarwood and smoke and everything I've been trying to deny for the past six weeks. His hands come up to my face, pulling me closer, and I can feel his heartbeat racing against my chest, can feel the tremor in his breathing.

When we finally break apart, I'm gasping.

"I love you too," I say, and it sounds like a confession and a surrender and the most terrifying thing I've ever said out loud. "And I don't know what to do about it. I don't have a framework for this. I don't have data to support it. I just have this feeling that's taking over everything and I hate it and I need it and—"

Marcus kisses me again, silencing the spiral before it can fully form.

"We'll figure it out," he murmurs against my mouth. "Together."

I want to believe him. I want to believe that love doesn't have to destroy you. I want to believe that the data—my body's honest response to his presence—means something beautiful instead of something catastrophic.

But as he pulls me toward his bedroom, as his hands move to the hem of my sweater, as the scent of cedarwood and smoke overwhelms my senses, I feel the first whisper of doubt.

Because there's someone who won't be happy about this.

Someone who's been watching me with increasing possessiveness. Someone who sees my thesis as a threat and my independence as a challenge. Someone who doesn't take kindly to being proven wrong.

My phone buzzes in my pocket. I ignore it.

It buzzes again.

And again.

Marcus pulls back slightly, noticing my distraction. "You should check that," he says.

I pull out my phone with trembling fingers.

Three text messages from Professor Ashford, timestamped over the last hour:

Need to discuss your thesis methodology. Concerning irregularities in your data.

Your personal life is clearly interfering with your work. We should meet to discuss your academic future.

Monday. My office. 9 AM. Don't be late.

The final message has a photograph attached.

It's Marcus and me from this afternoon, walking into his apartment building. His hand on my back. My head tilted toward his.

Someone's been watching us.
