I can think of many, really. True, my idea of good has more to do with strengh of character than kindness. I'm attracted to characters who DO the right things, before saying the right thing. But most of all, I love characters who stand up for their convinctions.
This said:
♥Hiroto from Tatta Hitotsu No Koi probably tops my list of the kind of guy I would have liked to meet myself.
♥Kai from Orange Days is just the right mixture of sweetness, candour and friendliness one can't help but be drawn to.
♥Tae Woong from The Snow Queen. Yes, I know, I may be "a little" biased in favour of Hyun Bin, but I dare anyone not falling for this character.
♥Chen Ling from MARS. Not your average "angel", but one carring a heavy burden. Yet he is wonderful, craziness included.
♥Ryosuke from Tokyo Wankei. The kind of silent, deep and strong guy who would protect you from harm at any cost.
♥Kang Ji Wook from Scent of a Woman. Although he starts off as indifferent to life in general, he soon becomes one of the bravest character I can think of.
