Okay, I hate heroes who commit noble idiocy in a romance: Ones who, upon falling madly in love with the heroine, can just push her away (pretend to no longer love her, etc.) when a major issue occurs (illness, bankruptcy, etc.).
Regardless of the reason, if the hero can give up or chase the heroine out of his life so easily, then he definitely can go on living without her. My favorite heroes are ones who, upon falling hard for the heroine, won't be able to cope without them. Ones who need the heroine so much that I can literally see them die if the heroine is no longer in their life. They wouldn't be very successful at committing noble idiocy because the heroine's part of their life line.
Dramas featuring these type of heroes (not in any type of order):
Ten Miles Peach Blossoms -Ye Hua
Game Rai Game Ruk -Charles/Saichon
New Tales of Gisaeng -Ah Damo
Healer -Jung Hoo
Bpoop Phaeh Saniwaat -Por Date
Song Huajai Nee Puea Tur -Tharatorn/Warong
Meteor Garden I -Dao Ming Si
Hana Yori Dango -Doumyouji
Be Strong Geum Soon -Jae Hee
Truth -Hyun Woo
Stairway to Heaven (Makjang to the max, but man is the main guy hot and so in love -tragic ending)
Prissana -Taan Chai (a little more subtle, but towards the end when he thought he lost her, he got very sick and almost died)
Summer's Desire -Ou Chen (don't find Peter Ho hot, but love his character too much from the original Chinese novel)
All of these hot powerful heroes listed above end up loving their heroine to pieces and definitely gave me the feeling that they wouldn't be able to go on without them. Any more dramas with a hero (prefer hot and rich/powerful ones) who, upon falling hard for the heroine, loves her so much that he won't be able to live without her in his life? Thanks :)
