As a fan of Rainie, I liked her paired up with Joseph Chang in Drunken to Love You. Hi My Sweetheart was cute too. (I actually dropped Sunshine Angel :P
i second drunken to love you thats a good one :) and heres a list of some of my favorite Taiwanese dramas maybe you might like some of them too ♥

Why Why Love is my favourite "Rainie" drama.  Mike He is also in it, as the male lead (bonus!).  LOL!  :P

Other Taiwanese dramas I would highly recommend are:

Autumn's Concerto
Fated to Love You
Hana Kimi
It Started with a Kiss
MARS
I like T-dramas but sometimes they can be corny :( If you like t-dramas try C-Dramas too... sometimes you can't even tell the difference
try:
Sunny Happiness
Hi My sweetheart (I have a sweet spot for Show Lo)
Fabulous Boys
Drunken to love you
invincible shan bao mei (although that one may be Chinese)

Don't drop sunshine angel I really liked it (cant remember why tho) and I am not a fan of really sad or dramatic dramas. Happy watching!!
I recommend Murphy's Law of Love
You can also watch Skip Beat! if you want something funny.
