hımmm...I did not check your list and I do not know if you are looking korean or japanese so I am randomly recommending you some...Tatta hitotsu no koi (romance), Heartstrings (romance, music,comedy), strawberry on the shortcake (romance, school)...I am guessing you have already watched cult stuff like Coffe Prince, Boys Over Flowers, Personal Taste or Secret Garden? well you reminded me, I shall watch Secret Garden again, my favourite:)
