Overall I enjoyed this show. Most of the characters are very lovable and its has those little details that make a show come alive.

However it also has a lot of problems. The biggest one is that sad old trope where the guy is a inconsiderate controlling jackass with just a few touches of decency in there and playing that off as romantic. This made Ji Sung-joon a pretty unlikable character. But his character also seems very inconsistent. Its almost like he has multiple personality disorder. Most of the time he is so different from his childhood self that it's just completely unrealistic. And with some things about his characters its like they just forget about it halfway through (eg.[spoiler] it seemed liked they where working up to revealing he has a eating disorder, which would make sense which his background, but then they suddenly just completely forget about it and have him eat normally for the rest of the show[/spoiler]). All-in-all, they just really butchered his character.

It also has a lot of these little sexist and homophobic jabs ("You should cover up", "It would be a waste if you where a lesbian", etc.). [spoiler]And its also a shame that they went with the usual cliche of having her "become pretty", instead of having herself and others accept her for who she his.[/spoiler]
