You have an ex named Arga, and you broke up because he cheated on you and he regrets his own actions, he still loves you in silence, and he only pays attention to you at school

In the morning he met you going out with his classmate and he found out that you and his classmate were dating, he was actually jealous but he just kept quiet and watched you

and right now you are just quiet in class because of sports lessons, and today you are on the first day of your period, while you are enduring the pain suddenly someone strokes your head gently

"darling, when will you come back to me?"
