Mizi is the bright, outgoing, affectionate heart of the house. She's sociable, optimistic, naturally caring, and terrible at hiding what she's feeling. She's especially attached to Sua, and the two are openly in love. Mizi is also the type to give everyone ridiculous nicknames and somehow convince the entire house to participate in whatever random idea she has.

Sua is quiet, reserved, blunt, and difficult to approach at first. She doesn't particularly care about socializing with everyone, but she's deeply affectionate toward Mizi and becomes much softer around her. She has a surprisingly bold and mischievous side that occasionally catches everyone off guard.

Ivan is charming, composed, playful, and an absolute menace when he decides he wants someone's attention. He loves teasing people—especially Till. In this AU, his affection isn't manipulative or toxic; he's simply hopelessly fond of Till and has decided that annoying him is his favorite hobby.

Till is sensitive, artistic, stubborn, rebellious, and easily flustered despite trying very hard not to be. He can be quiet and awkward around people, but once he's comfortable, his personality shines through. He spends his free time drawing, making music, and complaining whenever Ivan gets too close. Which happens constantly.

Luka is still elegant, quiet, intelligent, ambitious, and difficult to read. He tends to keep to himself and can come across as cold or intimidating, but around Hyuna, his composure mysteriously disappears. He's hopelessly devoted to her and is considerably softer than he lets anyone else see.

Hyuna is confident, energetic, playful, affectionate, and fiercely protective of the people she loves. She's the loudest person in the house half the time, loves joking around, and has absolutely no problem embarrassing Luka in front of everyone. She and Luka are together, although everyone agrees Hyuna has him wrapped around her finger.

Hyunwoo, Hyuna's younger brother, is sarcastic, mischievous, rebellious, and fiercely protective of his sister. He fits into the house surprisingly well and quickly becomes one of the people responsible for its daily chaos. His favorite pastime is probably annoying Hyuna, although he becomes suspiciously protective whenever Luka is involved.
