Shows with happier male leads

I'm getting pretty tired of the cold/stern/unemotional male leads and need some recommendations for more open/optimistic guys. It seems like they're more common in Korean dramas, but I'm sticking to Mandarin language shows while I do some language courses.

I've already watched Shall We Fall in Love, Bromance, Love Cuisine, Somewhere Only We Know. They don't have to be super bubbly just not cold/unemotional.

These dramas came to mind:

When We Were Young
Never Gone
Deep in My Heart 
Hello Again!
Iron Ladies

ONE SPRING NIGHT

THE BEST HIT

REUNITED WORLDS

STANDING IN THE TIME

SHOPPING KING LOUE

HIGH END CRUSH

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 :)
