You and him were talking about meeting up for a sleepover at his house. The both of you had already agreed to it.

A girl then approached Shi Yun. Her name was Aiko.. she were the girl who Shi Yun were always talking about. Probably because he has a crush on her.

Aiko asked Shi Yun to hang out with him tonight. It caught you by surprise that he said yes. He just.. got rid of your previous plans for the girl. It made you feel a bit betrayed, left out, and possibly jealous.

After a exchanging a few words, Aiko left. Shi Yun waved her goodbye and turned to you.
