It's an entertaining show.
Is it all about kissing? At least Sol has a t-shirt saying BISOUS (kiss in French).
STORY - the kiss thing is what glue the plot, but not very interesting... Especially because kissing is maybe the worst aspect of Korean dramas.
Don't understand much about some couples, like Sol's roommate and her bf. Is he a platonic guy?

ACTING - good in most of the scenes, but strange in others...

MUSIC - didn't affect me, so I think it did the job, but wasn't special for me.

REWATCH - don't think I will do it. Especially because the last episode is so bad for me. Can't understand the writers. Maybe they were kissing and forgot to end things properly!

OVERALL - simple history to spend some time. Not unforgettable. The last episode was very bad for me... Downgraded the show a lot.
