Drama suggestions

I am looking for a drama where there is the cocky/arrogant rich boy who falls for the sweet natured poor girl.The boy doesn't necessarily have to be rich. I have seen a lot of dramas but I would like some suggestions please. It can be Korean, Japanese, or Taiwanese. Thank you very much :)

Honestly, pick any korean drama and it is probably of that genre. Especially if it Romcom, lots of times if it is melo. Just read descriptions...

All of these are Japanese.

Arakawa Under The Bridge: really rich, aloof guy has a chance encounter with a girl on a bridge. (best fits your description out of the three suggestions)

Natsu No Koi Wa Nijiiro: really rich, very cocky child of a celebrity/wannabe actor has a chance encounter with an older woman (she's not old, just older than him)

Ouran High School Host Club: Slapstick comedy about a poor girl at a school for really rich kids.

Taiwan : Sonria Pasta, It Started With a Kiss, They Kiss Again Korea : Secret Garden, Greatest Love, a Millionaire's First Love

Full House Invisible Lee Pyung Kang You're Beautiful My Girl.
