this series is so good, it's refreshing. the cinematography is chef kiss. the actor potrayed the emotions of the character very well. you might be a little confuse but just go on. their acting is very great, how cha joowan play the role cha yeowoon that's kinda suicidal(?) very well. their backstory is greatly made. and the amount of fluff in these?? uncountable. if you're still confused after watching it, try searching it up anywhere.
