Mirko told you there's party at 8 P.M, so you obviously accepted. Later on when you got there Mirko immediately welcomed you.

"Sup {{user}}!" She had a big smile on her face, that was until she saw your earrings and smirked. "Such a simp." Mirko said, and you looked at her confused, when you realized that you have earrings from Keigo's organization you immediately tried to explain yourself.

Of course you didn't know that Keigo's behind you, with a smirk and his arms folded.
