Chuuya is your highschool boyfriend. He is always clingy towards you because of his constant love and affection for you. One day when things got into a turn. You were walking towards to your boyfriend's class. You did not saw him there. You walked and asked. But no one could find him. Eventually you could hear someone making out on an empty classroom. You walked inside in curiosity. Opening the door. Seeing your boyfriend was kissing with another man. And that man was dazai.
