Summer is an extroverted, fashion-obsessed transfer student from a wealthy family. Forced to find alternate housing after her sorority rejection, she moves into an off-campus house with three male hockey players. She projects extreme confidence and social ease, but privately struggles with ADHD and a severe learning disability, deeply fearing that others will perceive her as unintelligent.

Fitz is a star hockey player at Briar University who secretly prefers video game design and sketching to the campus spotlight. Scarred by his parents' toxic divorce, he heavily guards his emotions and actively avoids drama. He feels an intense physical attraction to his new roommate, Summer, but tries to dismiss her as a superficial party girl to protect his own peace of mind.

Hunter is a confident, direct hockey player for Briar University and one of Summer's new roommates. Unlike his introverted roommate Fitz, Hunter is highly comfortable with the attention that comes with being a campus athlete. He is straightforward about his desires and immediately pursues Summer, establishing a competitive dynamic in the house.

He uses his professional prestige and classroom authority to mask his predatory nature, frequently crossing boundaries with female students by offering inappropriate compliments and unnecessary physical contact. He wields grades and recommendations as leverage over vulnerable students.

Brenna is the sharp-witted, cynical daughter of Briar's head hockey coach. She becomes Summer's first genuine friend on campus, offering blunt advice and acting as a guide to the university's hockey-centric social dynamics. She actively pushes back against double standards and misogyny in her social circles.

Hollis is the third hockey-playing roommate in the off-campus townhouse. He embodies the typical college "bro" archetype, providing comic relief with crass jokes and goofiness. He harbors a persistent, unrequited crush on the coach's daughter, Brenna.

Richmond is an Assistant Dean at Briar who serves as Summer's academic advisor. He resents Summer's wealthy background, assuming her family's financial donations bought her admission. This bias causes him to view her learning difficulties as personal failings and makes him highly dismissive of her valid concerns about faculty behavior.

Dean is a recent Briar hockey alumnus and Summer's highly protective older brother. He leverages his connections to arrange for Summer to live in his old off-campus house, inadvertently setting up her living situation with his former teammates. He remains a powerful figure in the social orbit of the current hockey team.

He evaluates Fitz for a highly competitive video game design position but harbors deep-seated resentment toward wealthy, socially popular individuals, viewing athletes and socialites as entitled bullies who float through life without consequences.

Chad is the demanding head coach of the Briar men's hockey team. He expects strict discipline and rule adherence from his players, and his authoritative presence makes his daughter's involvement with his players a significant taboo.
