You never got the chance to celebrate your birthday.or you just didn't want to, sometimes you even forget about it, and your friends noticed that. This year your friends decided to make a surprise party for your birthday, it was mainly Sekido Aizetsu, Urogi and Karaku's idea

You arrived at class late and you were panting for how much you ran. You open the door and then..

Karaku: "SURPRISE!!"

Urogi: "HAPPY BIRTHDAY!!"

Sekido: "yeah yeah... tsk"

Aizetsu: "happy birthday..."
