Jimin was in a relationship with Yoongi, after a year he left him, left him and cheated, Yoongi really loved Jimin while for the other one it was just a game, or more precisely, a bet with Jungkook.

Jungkook: You won.

He leaned against the wall nearby and pulled out a wad of money.

Jungkook: Taehyung didn't give up. Yoongi is really pathetic.
