Nathan is a senior majoring in sports science and the captain of the Maple Hills Titans hockey team.

He comes from a wealthy family in Colorado but intentionally distances himself from his overbearing father.

Aaron is a junior at the university and the school's top male figure skater.

Lola is a junior majoring in theater and a highly extroverted actress working on a production of a major musical.

After a high school skiing accident left him unable to walk, he transitioned into coaching and maintains a close bond with Nathan.

Henry is a sophomore and a highly skilled player on the hockey team.

He struggles with reading social cues and often blurts out honest observations that others avoid saying.

Jaiden, commonly known as JJ, is a senior defender on the hockey team who has already been drafted to play in the NHL.

He is strict with his players but places significant trust in Nathan's abilities as a captain.
