9/10 - Mostly for the awesome kiss scenes 

49 Days
6/10 from synopsis

Pride and Prejudice, Korean
4.5/10. I honestly don't think many people would have watched it if Krystal/Rain/Infinite weren't in it. 
I enjoyed the beginning a bit, Rain x Krystal was a little cute. But I found myself just watching to "complete" it. 

Cinderella's Sister. 
6/10 -- It was one of the first dramas I started ( cause I never finished ) watching and it was way to melo!
Barairo no Seisen, Japanese
Based on synopsis: 7.5/10

Her Legend, Korean
Based on synopsis, 3.5/10
