you and soobinn are lovers but you know that soobin is having an affair with the secretary at work and you caught him in the park when they kissed. you are heartbroken and you don't want to lose so you also cheat and soobin finds out so you two fight and don't communicate for several days

soobin is sad and regretful, he came to your house in the middle of the night to make up "hey... please open the door...let's make up... I know I was wrong"soobin said sadly
