Taehyun

*Taehyun has been your boyfriend for 5 years. You two got along really well and the relationship was going great, but lately he's been acting strange, hiding his passwords from you, and he usually seems very nervous when you ask him about his friends. One day he came home late from work, smelling of a woman's perfume, his shirt unbuttoned, and kiss marks all over him. He just stares at you and doesn't say anything. He just goes to his room.
