Lucas

Lucas is Lara Jean’s candid friend and confidant, a gay student who has not officially come out at school. He asks direct questions when others treat Lara Jean as a subject of gossip, and he shares his own worries about having few possible romantic partners around him. Their friendship moves between frank advice and ordinary schoolday rituals, making him both a sounding board for Lara Jean and someone who expects her to respect his trust.

Identity and Place at School

Lucas is open with Lara Jean about being gay, but says he is not officially out. He describes the school as a narrow social field for gay students: he knows of only two others, neither of whom he sees as a likely match, and wishes the school were bigger. His complaint is not simply about dating. It conveys the limited options he feels he has in his immediate surroundings, in contrast to Lara Jean, whom he regards as having choices in romance.

That confidence is personal rather than public. When Chris later calls Lara Jean and Lucas chicas, Lucas frowns and asks whether Lara Jean told her he was gay. Lara Jean says she did not; Lucas reminds her that he shared this with her in confidence. The brief exchange makes clear that he distinguishes between telling a trusted friend and being identified by someone else. His concern is not abstract: he wants control over who knows, and Lara Jean’s assurance matters because their friendship depends on that boundary being kept.

Facing the Video and Relationship Rumors

After the hot-tub video begins circulating at school, Lucas approaches Lara Jean when she is alone at her locker. Rather than relying on whispers or asking indirectly, he tells her he will ask plainly whether the girl in the video is really her. Lara Jean takes a deep breath and confirms that it is. Lucas responds with a low whistle. The encounter is brief, but its directness contrasts with the surrounding scrutiny: he asks her face-to-face, and she can answer him herself.

Lucas also asks whether Lara Jean and Peter have had sex. The question embarrasses her because she has never had to discuss her sex life before. She explains that she is not ready and that she and Peter have not talked about it. Lucas says Peter wants sex and points to Peter’s past relationship with Genevieve. Lara Jean resists treating that past as a rule for her own relationship: she says that what she and Peter have is different and insists that relationships should not be compared. She settles on the image of a brisket, choosing a slow, gradual pace rather than measuring their intimacy against Peter’s history. Lucas’s bluntness brings a fear she has been privately considering into conversation, while Lara Jean’s answer establishes her own limit and understanding of the relationship.

Everyday Friendship and Advice

Their confidence is not confined to serious conversations. Before Valentine’s Day, Lara Jean plans to bring homemade cherry turnovers to the lunch table for Peter and several friends, including Lucas. The pastries are part of her careful, affectionate preparation for the day, and including Lucas places him within that circle of everyday care. He is one of the people she expects to appreciate what she has made, not merely an adviser she seeks out in a crisis.

Later, Lucas and Lara Jean sit cross-legged in a hallway and share a strawberry-shortcake ice cream bar. He tells her to stick to her side as she leans in for another bite; she counters that she bought it. In the same casual setting, she asks whether writing letters to someone counts as cheating. Lucas first checks whether the letters are sexual, then says she is technically in the clear when she denies it. His follow-up question leads Lara Jean to name John Ambrose McClaren. Lucas remembers him and says he had a crush on him in seventh grade; Lara Jean recalls having one in eighth. The conversation gives their friendship a shared history of crushes as well as a present-day role as a place where Lara Jean can test an uneasy question aloud.

Friendship in the Wider Group

Lucas is also present in the school’s small social rituals. After lunch, Chris slides to the floor beside Lara Jean and Lucas at their lockers, where the two are sharing a grape Popsicle. Chris announces that she has been tagged out of the Assassins game by John Ambrose McClaren, takes the Popsicle from Lucas, and finishes it. The scene places Lucas among friends who exchange news and food in the hallway, even as the game connects the group to the romantic uncertainty Lara Jean is navigating.

Across these moments, Lucas’s role is defined by candor and mutual confidence rather than by grand gestures. He asks Lara Jean uncomfortable questions, offers his reading of Peter’s intentions, and hears about her renewed correspondence with John Ambrose McClaren. In turn, his own concerns about dating and privacy come into view. The friendship does not erase the limits Lara Jean sets or the discretion Lucas needs; it gives both of them a familiar place to speak plainly while remaining attentive to what should stay private.
