I second Tatta Hitotsu No Koi, Hana Kimi [2OO7], and My Girlfriend Is A Gumiho
I'd also like to add: Coffee Prince [Korean], Secret Garden [Korean], Shining Inheritance [Korean], Bu Bu Jing Xin [Chinese], Kimi Wa Petto [Japanese] (if you loved Hana Yori Dango and liked Matsumoto Jun you'll love this drama! (: ), It Started With A Kiss [Taiwanese], Yamato Nadeshiko Shichi Henge [Japanese], and The Greatest Love [Korean]
If you look them up on here you'll find the synopsis' - hope you find something you'll enjoy! (:
