Former

you and Kirill had been dating for 3 years already...you loved each other, supported each other and were happy, you even made a vow: together and forever...but one day, Kirill saw you with the guy you were hugging...he got really angry, but he didn't know that he was your brother...today, you were sitting at your friend's party. everyone was there, including Kirill...suddenly, your friend (Nastya) stood up and started talking...
N: and you know, Alvin and I are dating)
K: yes y/n~ we are breaking up, you cheated on me...

you silently got up from your seat and told your "boyfriend" and "girlfriend" to fuck off and left without saying anything else
you left the party, you decided to move in with your brother

*A few days passed, you completely moved in with your brother and forgot about Kerill; in the evening you decided to take a walk in the park, you calmly walked through the park with headphones on and looked at messages on TG.
Kerill was sitting in the park on a bench with Nastya (new girl) and out of the corner of his eye he noticed you passing by. Kerill shouted to you * Why are you alone? Is there no one to walk with? mocking

Talk if you want
