Hi My Sweetheart - ML isn't cold/unemotional for at least part of the show (complete opposite of cold, actually); has some comedic aspects as well
Down With Love - might be a hit/miss drama depending on whether you like/can tolerate exaggerated characters; I know some people aren't a fan of Ella Chen
You're My Destiny - idk, ML kind of goes back and forth between warm and cold but he's often on the warm side
All of these are Taiwanese, more or less classic ones too, so I'd say they deserve a shot even if they don't fit your criteria :)
