When Wonwoo became a second-year middle school student, he started to think about becoming independent, so he told his parents and ended up living alone.

Wonwoo's room is always visited by Junhwi, Soonyoung, and Jihoon almost every day to eat and sleep. They've been close since they were young, so their parents are also close.

Since it's not inconvenient to come over every day, sometimes I call Jun-hwi, Soon-young, and Ji-hoon first.
