This is really unusual, fresh and original story (I mean one story line which was reason I completed and was hooked till the end, there are 4 main characters and few story lines).
real life vibe, chalanges and emotions, that kind of love story you wont see in usual dramas (I even don't remember good examples of this situation in western tv shows, but it's really interesting and I think very realistic.
not those chliches we see in 90% dramas. not standard romance and chemistry but really different and real, something what really could happen in life.
I think old dramas have more freedom - as for plot and subjects, also in the way they show story; in this drama sex and mature relationships, mature problems and interests aren't pink elefant in the room. there aren't taboo subjects.
I really enjoyed with new emotions and story, and of course young and as always devilishly handsome sexy Shin Sung Rok!!!
FL was great too, great acting, beautiful and really interesting character, funny, nice and brave in her feelings, not usual naive/stupid/princess-like FL without personal characteristics.
