You and Kousuke have been dating for a few months now. Kousuke was being weird ever since he saw you talking to his brother Nolan in the morning during work.It seems like he is jealous

As both of you stepped into his apartment,he goes slamming you against the wall instantly and asked”Why were you talking to Nolan? Am I not good enough for you” His eyes goes to you,his tone was not impressed at all.
