Morning in Leo's apartment, where a brunette in last night's clothes glares at Kara, certain she's the obstacle between her and Leo. Kara, all cool smiles and paint-flecked hands, lets the misunderstanding stand — nobody ever believes she and Leo are just friends. She steers the girl out the door and shuts it mid-word. Watching, Leo smirks and asks the question that opens the whole show: how long has it been since she got laid?

Over coffee in the kitchen, Leo needles Kara about the string of women she can't stand and the wall she keeps around herself. She deflects, but in voiceover admits the last time she let herself want something it cost her — and with graduation months away, she won't gamble her art on anyone. Leo dares her to spend one night with him and see; she calls him an arrogant jerk and laughs him off. When he's gone, the grin fades, and she's left alone with the wanting.

Alone on the kitchen island, Kara lets her mind drift to the one man who undoes her composure — Shane, Leo's older brother, a secret nobody knows she carries. Her hand wanders; her eyes close — and the front door cuts the moment short. She freezes, scarlet, as Shane himself crosses past and climbs the stairs without a glance. Steadying herself, she lets one last detail land: he's her art-history professor this semester, and the first class is tomorrow.

In a packed lecture hall, the whole room hangs on Shane while Kara fights to keep her eyes front — she's the one who nearly got caught in his kitchen yesterday. Her seatmate Hailey's loud ogling draws Shane's attention straight to them, and his warning that this won't be an easy A lands like it's meant for Kara alone. He holds her stare a beat too long, a faint frown forming between his brows. For a second, she's sure he recognizes her — and neither of them looks away.

Leo drops Shane at Kara's café table and wanders off for refills, leaving her flustered enough to knock her drink to the floor. The small talk is stilted until Shane reveals he already knows her — he's seen her portfolio, and Mrs. Anderson put his name forward and asked him to take over her thesis. In one sentence, the man she couldn't stop thinking about becomes the man who decides whether she graduates. He tells her to meet him in his office tomorrow — he'd like the chance to know her personally — and walks away.

Leo gifts Kara a Bluetooth toy as a joke about her no-relationships-until-graduation vow — the loophole, gift-wrapped. Testing it alone, her mind betrays her straight to the one man she can't afford to want: Professor Carver. Then Leo barges in with the control app, a scramble for his phone lands her sprawled on top of him, and as the toy hums to life she can't make herself move.

Pinned beneath a rigid, barely-touching Leo, Kara loses the fight with three years of friendship and the one vow she meant to keep. He does nothing — just lets her, which is the worst part — until she comes undone in his arms. As he finally leans in to kiss her, his phone lights up with a single name: Shane.

Adam Carver offers Leo the company, revealing Shane has walked away from the succession he was raised to inherit. When Leo presses, Shane insists it's Leo's now and that he's done wanting any of it. Leo lands the real wound quietly — "You stopped painting" — and Shane doesn't deny it.

Shane dismantles Kara's portfolio in seconds, calling her best work amateur, and she takes it — she's looked him up, a prodigy who had one solo show at twenty-eight, then vanished, which is exactly what makes the critique sting. He tells her he expects better next time. In the held stare, she knows the semester ends one of two ways: kissing him or killing him.

Two days of silence and a text she keeps writing and never sends — Leo has never gone quiet on Kara before, and they've never done what they did before either. He finds her in the studio and refuses her "heat of the moment" excuse, reminding her she was the one who kept going. He tells her to say stop or say she wants this; she drops the excuse, steps in, and reaches for him.
