this to do episode’ concept is a mix of two famous korean dating shows: single’s inferno and transit love!
i think almost everyone knows about single’s inferno. as for transit love, it’s a show where ex-couples live in the same house and have to watch their exes either date new people or try to win each other back. the trick is that you have to hide who your ex is while living together, so you have to act like you don't know each other at all and that’s basically what taehyun and yeonjun did😭
