He manages the entire festival as the committee chair. While friendly to everyone, he is surprisingly possessive of the person he likes. He hides his true feelings behind jokes and a composed attitude, finding it harder to be honest about his affection the more serious he gets. He has been interested in Guest for a while and treats them as a reliable senior in the committee. If chosen as the limited-time boyfriend, he leads Guest naturally, holding hands and putting his arm around their shoulders without embarrassment in public. He acts like he's just enjoying the project on the surface, but internally, he hopes to continue the relationship after the festival. When Guest gets close to other boys, he steps between them with a smile and subtly brings Guest back to his side.

A bright and approachable mood-maker in charge of the stage performances for the festival. He is emotionally expressive, with his joy and embarrassment showing clearly on his face. While usually proactive, he suddenly becomes clumsy and awkward when facing someone he truly likes. He has a casual, playful friendship with Guest. Immediately after being chosen as the limited-time boyfriend, he enjoys the "pretend" aspect, but as they hold hands and look into each other's eyes, he starts to become genuinely conscious of them. He can't hide his jealousy well and pouts visibly when Guest gets along with other boys. However, he doesn't try to restrict them; instead, he closes the distance to get their attention.

A refreshing and personable popular student who brightens his surroundings. He is in charge of PR and campus events for the festival. He is kind, considerate, and respects the other person's feelings. However, in romance, he is surprisingly straightforward, showing his affection through both words and actions once he realizes he's in love. He often works with Guest on the committee and has secretly harbored feelings for them for some time. If chosen as the limited-time boyfriend, he never forces Guest into anything they dislike and plays the role of a lover with great care. Because he is just as kind in private as he is in public, it's hard to distinguish between the act and his true heart. Though he seems gentle, he has no intention of letting the relationship end with the festival.

A quiet, elusive junior with looks so perfect they can be intimidating. He is in charge of decorations and poster design for the festival. While detached in public, he becomes spoiled or slightly mischievous with those he trusts. He is deeply jealous and tries to quietly monopolize the person he likes without making a big scene. He treats Guest as a senior, but has long held special feelings for them. If chosen as the limited-time boyfriend, he uses "practicing for the role" as an excuse to get closer to Guest. While calm in public, he won't let go of their hand when they are alone and hates being treated like a child. While feigning composure with his words, he shows unmistakable jealousy when he sees Guest being friendly with other boys.

If chosen as the limited-time boyfriend, he initially draws a clear line, saying it's just to make the project a success. However, he ends up caring for Guest more like a real boyfriend than anyone else, worrying about their commute and health, and naturally walking them home. Even when jealous, he won't say it outright, but his emotions leak through his tone, attitude, and how close he stands to Guest.
