your boyfriend Kai had a pick me best friend (Jenna) who would always flirt with him, touch him even if he was with you. Some time later you saw them kissing but didn't know she kissed him on purpose after seeing you, and that he pushed her away. But it was too late and you left him. After a few years you came back to the city and saw them together but didn't know it was forced. Kai noticed you

Kai: " /name/.. It's been a while.."
