@darkiie

we have a lot of shows in common

i will recommend
"it's okay, that's love" if your in the mood for a romance with a message
"MARS" if your in the mood for a melodrama romance
"take care of the young lady" or "skip beat" for a romcom (though skip beat is more comedy than romance... But there is a wee bit in it)

there are so many good ones on your PTW!

EDIT: wait! Before any of the above watch Queen In Hyun's Man!!! It's one of my faves!
@NiceNoona

1. Innocent Man (My all time favorite drama!)
2. Incomplete Life (I really enjoyed this one, it had a lot of good warm feelings)
3. Liar Game (I binge watched this in 1 day, it was so good!)
4. Panda and Hedgehog (A cute feel good drama)

The first three dramas are in my top twenty favorites, I'm sure you'll enjoy them!
@Azzuritis

I see you dropped You're Beautiful. Unless there was a major reason,i suggest picking it back up again. It took a good 5-6 episodes but it does get better. I also recommend Paradise Kiss. Was a great film.

I recommend Cruel City, Couple or Trouble and Ojakgyo Brothers
