Hana Yori Dango... 
Hotaru no Hikari with Ayase Haruka.
My first drama was Hana Kimi. My favourite :)
Rich Man, Poor Woman
Sekachu aka Crying out love in the center of the world. Still one of my favorites
My first one was SO FREAKING good it was called Sexy voice and robo. 
Mine was Hana Kimi, which made me fake illness so I could stay home from school and watch the drama instead. :D 
imouto yo or heaven's coin. 
Kamisama Mou Sukoshi Dake
Boku no Ita Jikan (My remaining life time ) -  it made me watch more J-Drama right away :)
