The reincarnation storyline in this drama may very well be one of the most interesting ones I've seen for a BL (Since there really isn't much diversity). However, even though I had high hopes for this drama, it fell short of my expectations.

Pros:
1) Great storyline idea (Reincarnation)
2) Cute Side Couple (Team and Win ahhhh)
3) Good acting in some scenes (Particularly Pharm in the last epi)
4) Nice music use (esp in first epi around the start). I really like the acapella song in the first epi, brought me to tears though it did get slightly irritating in later scenes.
Cons:
1) Main couple's acting was quite flat, esp Dean IMO. His face didn't really move much throughout the entire show? But his character did not really have much personality so :/ Pharm did relatively well considering the fact that he had to do so many crying scenes.
2) DRAGGY. This is the main reason I did not enjoy this drama. The dialogues were slow with many pauses and there were many unnecessary scenes where nothing was happening. I had to press 'skip' way too many times.
3) Not much chemistry. Though I feel there were cute moments, there wasn't any scene that made my heart flutter and I just did not feel that the to main actors were close at all.
4) Storyline/Plot esp towards the end. The conflict in this drama was put at a very weird point (Not gonna say where in case it's considered a spoiler) and resolving it took like what, 15 mins of the show? The conflict IMO is also slightly illogical though one can reason that Pharm was very overwhelmed by his emotions then, I just don't think it justifies his actions.

All in all, this is a drama that started out great but got boring and deteriorated as the episodes went on.
