Up to Episode 5 nice, feel good drama with cute leads and sufficient plots to keep interest going. Lee Sung Yeol's haircut certainly does him no favours. Is he trying to disguise his good looks??? Right, at ep. 8: Some people mention cute, fluffy romance, but around eps. 8 and 9 this gets really heavy……around eps 11 and 12 etc my feeling is a) why the heck are people so unkind/nasty to each other? and b) why don't they explain what happened instead of minds just going into overdrive based on false assumptions due to others' silence? - well I suppose then there'd be no excuse for 20 episodes, silly me. I put it on hold around the middle as, like others, it did not seem to go anywhere. Went back as I liked the lead actors and side stories of the others. Liked Mrs Ahn too, but maybe that's my bizarre taste. At ep.17: after some going round in circles around the middle, interest picks up. I've decided I really like this series and care about what happens to the characters but it certainly is not a laugh a minute, it can get quite depressing if you are in the wrong mood. Also the supernatural theme is there but is irritatingly background and not developed. Finally having reached the end and the denouement is certainly cleverly thought up. It's really not a spoiler to say nicely done, sweet. harmony and bliss descends. Better haircuts and appearance (within its limitations) virtually all round. As others say, it's quite emotional (I'm so happy (cry, cry where's that tissue box?) )HOWEVER, since most of this series from episodes 8/9 to near the end was more like tragedy or melodrama and after the contortions of the plot and characters, the transformation in one single, final episode was really a cheat. The trouble is the series went on in the middle for far too long. If there were fewer episodes, the ending would have been more in proportion and credible. Still it was a nice ending and I enjoyed it overall and am glad I didn't drop it half way through.

Music OK but too sentimental, not so great you wanted to continually hear it to the point of depression. Re-watch - probably not for me, it's too long a slog, with too many episodes going round in circles. For the good bits (generously overlooking the bad bits) 9/10 overall.
