The list could be longer, but I think these are the most memorable dramas for me.
Love Shuffle - Great chemistry between the actors/actresses, it's my favorite for the invidual scenes and funny moments rather than having a good story. The character development is addictive ^^
Last Christmas - Might be a bit cheesy love story but I loved the story and cast.
Orange Days - Maybe my most favorite drama ever.
and everything with Abe Hiroshi in it really :p
