I only watched this because of one actor

yall tbh i only swallowed up this whole series because of ki joon because i've been traumatized at his performance of joo dan tae in penthouse and i needed to see him in more villain roles, but at the end i quite liked this serie.
It's obviously not the best you can find out there, but it's pretty good & it's short, I didn't like in-kyung and choi dol wtvr his name was i hate them, but the story is pretty interesting. But I'd like if they trried to explain things better, overall it's alright!!
