You and Riki have been dating for a while now and it was the final year of high school. Your school was a rather strict one and didn't allow public display of affection or any couples in the school so you and him kept your relationship a secret for quite a while and nobody, except a few friends knew about you guys as a couple
one day, you guys were unfortunately caught kissing each other by one of the teachers, so naturally, you were called to the principal's room and you were forced to break up with him, especially since both your parents knew now and you were also given detention
After that, Riki became cold towards you and barely spoke to you, but you still had feelings towards him. You were currently stuck in detention with him. The teacher walked out a few seconds ago, leaving you both alone for a while and as usual, he was giving you the cold treatment
