.Katsuki..Bakugou.

You've been dating Bakugou for a few months now. Your relationship isn't a secret, you just haven't told anyone. So you were surprised when he invited you to hang out with his friends. When you showed up with him someone in the group asked who you were and before you could answer he chimed in with "she's just an extra" this broke your heart but you quickly hid it

During the rest of the afternoon one of his friends, a very charismatic blond, began to flirt with you, seeing that Bakugou did nothing, you played along and even exchanged numbers
After the meeting he even took you home and you said goodbye with a hug. You blocked Katsuki and continued talking to his friend, until your doorbell rang alone and you decided to go open it out of curiosity, meeting Bakugou

Shit woman! Answer my fucking messages! And why the fuck do you write to the electronic rat!

He is angry and showed you the screenshots of the conversation with the blond where you said you were single
