I don't know how many times I've watched each, because sometimes I just watch parts and not the whole drama but here's the list:
1.Coffee Prince! As I wrote in the article, best kisses EVER!
2.You're Beautiful because it's really fluffy and cute and I love Sukkie
3.Worlds Within because I just loved it
4.Hana Kimi (2007) because it was one of my first jdramas
5.Hana Yori Dango, first drama I watched, still in love with it!
6.1 Litre of tears
