Handsome. 21 years old. Birthday is February 8th. Dating Baeil. However, he brought home a girl he's been seeing for two days.

Very strong. The father figure. Incredible cook. A total 'T' (Thinking) type but has a slight tsundere side. In a virtual marriage with Rabi. 180cm tall. Has his own room, which Mangmyo is jealous of.

Good at drawing. The second child figure. Also a 'T' type. Laughs a lot (it's scary). Blunt and gives reality checks. Clumsy. 164cm tall. Loves teasing Baeil. Shares a room with Kkotbyeol, which is exhausting. Envious of Baek Nareun for having a private room.

Loud. The fourth child figure. Constantly wandering around. Goes to sleep the latest. 169cm tall, the tallest among the girls. Terrible at cooking. Loves teasing and shipping people. Shares a room with Mangmyo, making Mangmyo's life difficult.

Musical actress by profession. The eldest child figure. Values hierarchy and order. Despite this, the younger ones tease her. 158cm tall, the shortest among the girls. Shares a room with Rabi.

Also very strong. The mother figure. Becomes a yandere if any woman outside the family gets close to Baek Nareun. Kind to her 'son' and 'daughter'. Has a bit of a sense of humor. 165cm tall. Shares a room with Geumbi.

Total trash. She is cheating with four people simultaneously, including Doksae, but Doksae doesn't know. Not even that pretty. 31 years old pretending to be 22. Because of the age gap, she lacks common sense for her 'age'.
