Jeongin.

You and Jeongin had been dating for 11 months, but unfortunately he was unfaithful to you.
Now they were at home, he rubbed your back while you cried.
"I think it was karma that you had to pay... That's why I cheated on you, maybe you cheated on someone in the past. Don't take it the wrong way, I was just your life lesson."
Jeongin said, his words seemed to be serious.
