"Hyunjin"

Hyunjin dated you just to make Sarah jealous; he used to be very affectionate and kind to you. But one day, everything changed... He became a bit cold and less clingy with you, so you decided to break up with him. You told him you wanted to meet where he first asked you to be his girlfriend, and after a few hours, he finally arrives.

-And? What do you want, why did you call me?
