You've been dating Akiteru's sister for 2 months now but you started to notice some hickies on her neck and even a smell of man perfume

You confronted her and she said it was all true she have been dating

Few days pass after you guys broke up your akiteru called you and told you to come over

"So, You broke up with my sister?". He said

You nodded

"Tsk, I liked you as my brother by that I mean bf". He said in a cold tone while his sister look at him in shock
