Clumsy girl & Bad boy

Hey guys,
I am new at watching asian Dramas. I started with Cinderella and the four Knights and I was addicted to it. Eun Ha Won & Kang Ji Woon forever lol. After this Drama I've watched Cheese in the Trap also Kdrama . I want to see something new I mean from Japean or other asian Countries. Do you have any Tips for me? In love Slaissene :)

If you are new to Kdrama then I highly recommend: My Love from Another Star, Secret Garden, goblin. Those are highly addicting dramas. And quite good. 
if you want light coming of age dramas with the bad boy-clumsy girl plot, then try Monstar and Reply 1997.

But for Chinese drama I recommend is Love O2O and boss and me. Also try taiwanese dramas Meteor Garden and Fated to Love You
for Japanese drama, if you want that Bad Boy clumsy girt dichotomy then try: the Black devil and the white Angel... and then Good Morning Call.

I think these will fit what you're looking for.

There's a taiwanese movie called Our Times where the girl is "nerdy"/clumsy and a bad boy :) It's very popular and sweet, you're gonna like it.
