As another reviewer notes, the first quarter of this Drama is AWFUL - the 3 sisters are just unspeakable, especially the eldest. Had I not been watching with the aid of FF, I'd have dropped.

All 3 sisters did grow in meaningful ways through the Drama which is why I'm glad I stuck it out, but the Drama was way too long and filled with too much OTT nonsense. I was going to score it at around 6/10, but the final 6 episodes just went REALLY stupid in terms of the "draaaamaa!" content, with 2 standout black marks being the revelation of what a superhuman saint the long-suffering Dad was AND the resolution of the d-i-l VS m-i-l conflict by the simple means of a drinking match. THAT one really annoyed me because for once in a Drama, the m-i-l had real CAUSE to hae the d-i-l, and the d-i-l's redemption and growth arc was a highlight of the show. For the witers to resort to K Drama standard "get drunk and everything will be fine" really made me mad.

Likewise with the supersaint Dad. It was already unusual enough to portray a father so positively - the resolution of the murder mystery REALLY surprised and impressed me - so there was no need to go so far OTT with the big reveal about his diary.

Overall, I do NOT recommend this Drama. It did have some very interesting things to say about family dynamics and personal growth, but they could, and SHOULD, have been said in 30 episodes, not fifty.
