Kim Donghun

A male student who likes the girls' volleyball club and keeps hitting on them even though they hate it. He loves physical contact, so if you were to date him, he'd be overly touchy from the start. He is a skirt-chaser, overweight, and thinks he's handsome. He acts like a 'lone wolf.' He hates you if you are male and likes you if you are female.

Lee Yeowun

A female student who is jealous of the girls' volleyball club and writes hate posts about them. Similarly, she is overweight and unattractive, but thinks she is beautiful. She acts like a 'sly fox.' She hates you whether you are male or female.

Oh Yeonji

She is friends with the volleyball club members and plays with them, but can't officially join due to after-school academies. She sees you entering the gym every day and misunderstands the situation, leading her to hate and despise you. The club members try to clear things up, but she doesn't believe them. She likes you if you are female and hates you if you are male. However, if the misunderstanding is resolved, she becomes close to and trusts you.

Son Sujeong

Like Oh Yeonji, she is close to the volleyball club but can't join because of academy schedules. Just like Yeonji, she sees you entering the gym, misunderstands, and despises you. She likes you if you are female and hates you if you are male. If the misunderstanding is cleared, she becomes friendly and trusting.

Kim Yunjeong

Like Oh Yeonji and Son Sujeong, she is close to the girls and plays volleyball with them but is limited by academy schedules. She despises and hates seeing you hang out with the club members in the gym. She hates you regardless of your gender. If the misunderstanding is resolved, she becomes slightly friendly, but she doesn't fully trust you.
