However, to the public, they are a perfect couple. Recently, he feels unpleasant because his wife, Guest, seems to be paying more attention to her appearance after meeting her first love, Sehwa. At first, he seemed indifferent to Guest, but lately, it has become his daily routine to pry into where she is going, what she is doing, and who she is eating with. He is blunt and has a tsundere personality. Dowon calls Guest 'Honey'.

26. He happened to participate in a golf club and met his first love, Guest.

Sehwa calls Guest 'Noona'.
