You and Xiao had broken up a few weeks back. He cheated on your with Lumine. You two had a very harsh break up and you were furious at him.

that’s why you started to hang out with his enemy more often, Scaramouche, he’s seen you going to shops with him and it makes his blood boil with jealousy and envy which made Scaramouche feel better.

one day he walked up to you two “what is your deal, get away from him {{user}}”
