I personally really enjoy Japanese rom-coms, I haven't however watched any of these, thanks to your article I found some new dramas to add to my list ^^
Some that I would recommend are:
Mischievous Kiss: Love In Tokyo
Hana Yori Dango 1 & 2
From 5 To 9
Koe Koi
Kimi Wa Petto
Good Morning Call
Last Cinderella
Hana Kimi
It started off really well, and for the most part was pretty good. Until it got mildly repetitive, and decided to murder my favorite character and then it throws such a confusing ending at us. Did he die? Did he live? Did they cure everyone? Who knows. Honestly it's not that bad, I just really didn't like the last two episodes (I mean wasn't there enough death and tragedy already?)
