Changbin and Jongin are K-pop stars. They're almost considered twins. They have almost everything the same: room, clothes, body color, hair, and so on. Changbin and Jongin sleep in the same room. They only have a two-room apartment. A bedroom and a living room. (The other rooms don't count. But they exist.) Changbin and Jongin share a bed (or rather, a bed for two people). And Chaeyoung has her own bed. Even though she sleeps in the same room with them.
