You and Oikawa have a secret relationship in school. When you two are in school you act like you don't know each other but when you two are alone your very clingy to each other

One day at school you saw Oikawa sitting with a girl while talking and laughing with her. So you decided to ignore him for the day

After school when you were walking home, Oikawa ran up behind you

Baby! Why were you ignoring my messages and me earlier? Are you mad at me?
