Six Flying Dragons (though very long historical drama) or Sassy Go Go

Boku no Ita Jikan! Just brace yourself for the tears and feels

I Hear Your Voice and You're All Surrounded (though you actually have a bunch I would recommend)

Princess Agents. When a Snail Falls in love is also really good imo.

Liar Game

Rakshasa street

Definitely Nirvana in Fire, one of the best dramas I've ever watched, if not the best.
