Skip Beat (However was not in Japanese but based on manga and anime)..Seeing the live action was wonderful, then I found more dramas and love all the romance
First K-Drama is You're Beautiful, a great way to start watching K-Drama, it was amazing. First T-Drama is Sotus the Series, i'm completely in love with it!
My cousin was the one that open my eyes about the beauty of Asian dramas and Kpop. She started me with One liter of tears and we followed with Werewolf boy (movie) But once she left (she lives in another city and she was visiting me) I started on my own with You're Beautiful.
My first drama was Marmalade Boy the Taiwanese version. However my first Japanese drama was Hana Kimi. Never looked back after that. But, gosh I wish they would make a Japanese version of Marmalade Boy.
