Professor Ashford's office smells like old money and disappointment—his disappointment, specifically, which he wears like cologne.

I sit across from his mahogany desk, my thesis proposal clutched in a folder that suddenly feels very small. The office is all floor-to-ceiling bookshelves and leather-bound spines that probably haven't been cracked open since the Clinton administration. Everything here is designed to make you feel inadequate. The Persian rug. The Ivy League diploma. The way he's looking at me over the rim of his glasses like I'm a problem he hasn't solved yet.

"The Love Hypothesis," he reads aloud, his tone suggesting he's just discovered the title written on a bathroom wall. "You're proposing to prove that romantic love is... what exactly? Fake?"

"Not fake," I correct, my fingers digging into the armrest of his chair. "Neurologically constructed. A behavioral conditioning response to evolutionary pressures and chemical stimulation. Love isn't an emotion—it's a biological algorithm."

He sets the proposal down with the careful precision of someone handling something mildly toxic.

"Iris." He sighs my name like it's a burden. "This is derivative. Dutton's work on neurochemical bonding, Fisher's attachment theory—you're not saying anything new."

Of course he'd say that. David Ashford has built his entire career on the premise that love is transcendent, ineffable, beyond the reach of empirical measurement. His books are full of flowery language about soulmates and destiny. They're bestsellers precisely because people want to believe his bullshit.

I'm here to prove it is bullshit.

"My methodology is novel," I say, keeping my voice level despite the way my pulse has picked up. "I'm proposing a controlled social experiment where I'll systematically condition a subject to experience the neurological markers of romantic attraction. By manipulating environmental factors, proximity, and behavioral reinforcement, I can artificially generate the exact same chemical cascade that people mistake for love."

"And if you succeed?" He leans back in his chair, steepling his fingers. "You'll have proven that love is... what? Manipulable? That's not exactly groundbreaking."

"I'll have proven it's not real," I snap. "That it's just dopamine and oxytocin and a survival mechanism we've romanticized into something transcendent. That's the entire point."

Ashford studies me with an expression I can't quite parse. It's not quite contempt, not quite pity. Something worse—something that feels like he's seeing through me, past the armor of logic and sarcasm to whatever broken thing is underneath.

"You're very young," he says finally. "And very angry at something you're calling love."

The words hit like a slap, and I hate myself for flinching.

"My personal feelings are irrelevant," I say coldly. "The hypothesis is sound."

"Is it?" He stands, walking to the window that overlooks the quad. The late afternoon light catches his silver hair, making him look like he stepped out of a catalog for distinguished professors. "Tell me, Iris—what happens if you're wrong? What if, despite your best efforts to reduce love to chemistry, you discover it's something more?"

I don't answer because I can't. Because the possibility terrifies me in a way that has nothing to do with academic integrity and everything to do with the fact that my mother asked me the same question once, right before she drank an entire bottle of wine and called my father's mistress at three in the morning.

"That's not going to happen," I say instead.

"No," he agrees, turning back to face me. "I don't suppose it will. Not if you don't let it."

There's something in his voice that makes my skin prickle. It's almost kind, which somehow makes it worse. Kindness is a weapon in the hands of people like Ashford—people who use it to make you feel like they understand you, like they're on your side, right before they use that understanding against you.

"So you'll approve the thesis?" I ask.

"I'll need to see your subject selection criteria," he says. "And I want weekly check-ins. This kind of work requires supervision."

Of course he does. He wants his hooks in me, in my project, in every aspect of what I'm doing. I can see it in the way his eyes follow me as I stand, gathering my folder. I can smell it in the air between us—that particular cologne mixed with something darker, something possessive.

"Fine," I say. "I'll have the criteria to you by Friday."

I make it to the door before he speaks again.

"Iris." His voice stops me cold. "Be careful what you try to prove. Sometimes we're motivated by things we don't understand, and we rationalize them as logic after the fact."

I don't turn around. I just leave.

---

The walk back to my dorm is a blur of campus architecture and my own racing thoughts. Ashford is wrong. He has to be wrong. I've spent my entire life understanding the mechanics of human behavior, the way people fool themselves into believing in grand narratives when the truth is far simpler: we're just meat responding to chemical signals, nothing more.

My mother didn't love my father. She was addicted to him—to the dopamine spike of his attention, the oxytocin flood of physical intimacy, the cortisol crash when he withdrew. She confused addiction with emotion, and it destroyed her.

I won't make that mistake.

The bar is crowded when I get there, which is good because it means Sophie will be too distracted to ask why I've shown up on a Tuesday night looking like I've been chewed up by my own thoughts. The Crimson Tap is the kind of place where undergraduates come to pretend they're sophisticated while drinking beer that tastes like regret. Sophie works here part-time, and she's currently pouring a cosmopolitan with the kind of precision that suggests she actually cares about cocktail ratios, which is very Sophie.

"Hey, babe!" she shouts over the noise, her face lighting up. "You look like you need a drink!"

"I need something stronger than a drink," I mutter, sliding onto a barstool. "I need a lobotomy."

"Ashford again?" Sophie doesn't wait for confirmation before she's already mixing something. She knows me that well—knows that Ashford and I have a particular kind of dynamic that leaves me feeling scraped raw. She also knows better than to push, so she just sets a vodka soda in front of me and squeezes my shoulder.

I'm reaching for the drink when I see him.

Marcus Reid is at a corner table, and he's doing what Marcus Reid does best: being the center of gravity in a room full of people who orbit around him like he's the sun. There are three girls draped across the booth with him, and he's looking at each of them like she's the only person in the world. The way his mouth curves when he laughs. The way his hand rests on one girl's back, casual and intimate. The way his eyes—that impossible gray-green that I've only seen in person twice—crinkle at the corners.

He's intoxicating to watch. Not in the way people usually describe beauty—I'm not interested in his symmetrical features or his effortless athleticism. It's something else. It's the way he makes it look so easy, like he's cracked some code that the rest of us are still desperately trying to understand. Like he knows something about human connection that we don't.

And then he looks up, directly at me, and smiles.

It's not a smile for me, exactly. It's a smile he's giving to everyone and no one, a smile that's practiced and perfect and designed to make the recipient feel chosen. But it lands on me like a physical thing, like a touch I didn't consent to.

Sophie notices me noticing him and makes a small noise of disapproval.

"Don't," she says.

"Don't what?"

"Whatever you're thinking. I can see it happening in real time, and I'm begging you not to do it."

I tear my eyes away from Marcus and focus on my drink. The vodka burns going down, which is good. I need the distraction of physical sensation, something to anchor me to the present moment instead of the idea that's crystallizing in my brain with the clarity of a hypothesis finally forming.

"What if I told you I had a thesis problem?" I ask carefully.

"I would tell you to talk to Ashford."

"No. A different kind of problem. A subject problem."

Sophie sets down the glass she's been polishing with the kind of deliberation that suggests she already knows where this is going. "Iris. No."

"You don't even know what I'm about to say."

"You're about to tell me that you want to use someone for your experiment. Someone specific. And I'm telling you that's a terrible idea."

I take another sip of my drink, considering. Sophie is right, of course. Sophie is usually right, which is annoying because it makes it harder to dismiss her concerns as emotional rather than logical. But she's also the only person in my life who knows about my mother, about the way I watched her dissolve into someone unrecognizable when my father left. She's the only person who knows that this thesis isn't academic for me—it's personal.

"What if it's the perfect idea?" I say quietly. "What if the person I choose is someone who's already engaging in exactly the kind of behavior I want to study? Someone who's naturally gifted at manipulation and seduction?"

"Iris—"

"Someone like Marcus Reid."

Sophie actually puts down the glass. I can see her working through the logistics of this in real time, can watch her come to the same conclusion I have: Marcus is the perfect test subject. He's spent his entire college career conditioning people to fall for him. He's a walking case study in behavioral conditioning. And more than that—he's the kind of person who uses people because he's terrified of being used, which means he's incapable of genuine connection. He's proof, walking around in an expensive cologne and a vintage band t-shirt, that love is just chemistry and manipulation and survival instinct.

"This is a bad idea," Sophie says finally. "This is a catastrophically bad idea, and I'm saying that as someone who loves you."

"It's a hypothesis," I counter. "A testable, falsifiable hypothesis. I reverse-engineer exactly what he does to make people fall for him, and then I document the process. I prove that love is constructed, not felt."

"Or you prove that you're capable of hurting someone."

I flinch at that, but I don't argue. Because Sophie's right about that too—there's a cruelty in what I'm proposing, a fundamental disregard for Marcus's autonomy that mirrors exactly what Ashford does to me. But that's not the point. The point is that I'm right. The point is that I have to be right, because the alternative is admitting that love is real and I'm terrified of it.

"One drink," I say. "I'm going to have one drink with him, and I'm going to assess his suitability as a subject."

"Iris, no—"

But I'm already moving, already sliding off the barstool with a confidence I don't feel. The bar suddenly feels very small, and Marcus Reid is very close, and I'm very aware of the fact that I'm about to do something that will either be brilliant or catastrophically stupid.

Probably both.

He notices me approaching before I've made it halfway across the room. I watch him excuse himself from the girls with the kind of smooth, practiced ease that suggests he's been waiting for an escape route. He stands as I reach the table, which is surprisingly gentlemanly for someone with his reputation.

"Iris Chen," he says, and hearing my name in his voice is like a small electric shock. "I don't think we've officially met."

"We haven't," I confirm. My heart is racing in a way that has nothing to do with the vodka and everything to do with the fact that he smells like cedarwood and smoke and something wild that I can't identify. "I'm working on a research project, and I think you might be the perfect subject."

One of the girls at the table makes a small, wounded sound. Marcus doesn't even glance at her.

"A research project," he repeats, a smile playing at the corners of his mouth. "That's a new line. I like it."

"It's not a line. It's the truth."

"Even better." He gestures to the empty seat across from him. "Tell me more."

I sit down, acutely aware of Sophie watching me from behind the bar like I'm a car crash about to happen. The table is small, and Marcus is large, and there's maybe six inches of space between us. I can feel the heat coming off him, can hear the slight catch in his breathing when I lean forward.

"I'm studying behavioral conditioning," I say, keeping my voice level. "The way people manufacture emotional responses based on environmental cues and systematic reinforcement."

"Love," he translates. "You're studying love."

"I'm studying the illusion of love."

"Harsh." He's still smiling, but there's something sharper in his eyes now. Something that suggests he's not as shallow as his reputation implies. "And you think I can help you prove it's fake?"

"I think you've spent your entire college career conducting an informal experiment in exactly this phenomenon," I say. "You've perfected the mechanics of attraction. You know how to make people feel things that aren't real."

"Maybe I just know how to make people feel things that are real," he counters. "Maybe you're the one who's wrong."

The words land with more impact than they should. There's a moment—just a moment—where I let myself consider the possibility that Ashford was right. That I'm motivated by something I don't understand, and I'm rationalizing it as logic after the fact.

Then I push the thought away.

"I need a subject," I say. "Someone who's willing to let me document their behavior in a controlled experimental context. Someone intelligent enough to understand what I'm doing and interested enough to participate anyway."

"And if I say yes?" Marcus leans back slightly, creating just enough space that I can breathe again. "What exactly does participation entail?"

"Meetings. Observations. Behavioral modification based on psychological principles."

"You want to manipulate me," he says, and there's amusement in his voice. "You want to conduct an experiment where you deliberately try to make me fall for you."

"Yes," I confirm. "Exactly that."

He's quiet for a long moment, studying me with an intensity that makes my pulse race. I can see him working through the implications of this, can watch him come to the same realization I have: this is dangerous. This is a game where both of us could get hurt. This is the kind of thing that destroys people.

"Okay," he says finally. "I'll do it."

"Just like that?" I didn't expect him to agree so quickly. "You don't want to think about it?"

"I don't need to think about it." He leans forward again, and the space between us collapses. "I've been waiting for someone like you, Iris. Someone who thinks they can figure me out. Someone who thinks love is a problem to be solved instead of a mystery to be lived."

The smell of him is overwhelming this close—cedarwood and smoke and something darker, something that smells like danger. My heart is racing in a way that has nothing to do with my hypothesis and everything to do with the fact that I'm in way over my head.

"When do we start?" he asks.

"Tomorrow," I say. "Coffee. Ten a.m. The place on Fifth Street."

"It's a date."

He says it like a threat, and I realize with a clarity that feels almost painful that I've made a terrible mistake. Not because my hypothesis is flawed, but because I've just volunteered to spend time with someone who might actually see through my defenses. Someone who might actually crack me open, despite everything I've done to prevent exactly that.

I stand up, needing distance, needing air.

"Iris," he says as I'm turning to leave. "I think you should know—I'm going to win this experiment."

"You can't win a scientific study," I say coldly. "There's no winning or losing. There's only data."

"We'll see," he says, and he's smiling that perfect smile again, the one designed to make you feel chosen. Except this time, I think it might actually be for me.

I walk back to Sophie without looking back, but I can feel his eyes on me the entire way.

"You're insane," Sophie says flatly. "You're actually insane, and I'm going to have to stage an intervention."

"It's fine," I say, but my hands are shaking as I pick up my vodka soda. "It's a controlled experiment. I'm in complete control."

Sophie gives me a look that suggests she knows exactly how much control I'm about to lose.

"This is going to destroy you," she says quietly. "And I'm going to be here to pick up the pieces, and I'm going to say 'I told you so' approximately six thousand times."

"Noted," I say.

But I'm not listening anymore. I'm thinking about cedarwood and smoke and the way Marcus Reid said my name like he already knew all my secrets. I'm thinking about the fact that I have no idea what I'm doing, and for the first time in my life, I'm not sure that logic is going to save me.

I'm thinking that maybe—just maybe—I should be terrified.
