Hmm from your PTW list..
Romantic Princess (If I remember it correctly, its not exactly light and fluffy, but its not real heavy either)
Fated to Love You- I loved this drama, it is kinda heavy, but not in a way thats going to throw you off.
Sunny Happiness-Its a good watch, it goes by kind of fast.
Ouran High School Host Club- Its just silly, a good mood breaker.
Sidenote: I like your avi.
