The story is exactly my cup of tea huehuehue. Hate to love, casual sex partners to the point that they squabble even while doing it. Even nicer since they're coworkers! Well, just as I thought, the ex is coming back to uke's life. I really thought it'd be at work though. Although I was already sure it was him when a blind date was mentioned. Or if not, then any of the other exes.
Edit: Well, shit coz he's really using work to go back to uke's life.
Edit: finished it and omg season two Hyunwoo is perfect!
You and I can't do this
