I haven't seen much from your PTW list, but I recommend
Gokusen,
The Princess' Man,
The Greatest Love,
Kimi wa Petto,
Tatta Hitotsu no Koi
and the movie A Werewolf Boy
I also suggest you pick back up Gu Family Book (there's a lull in the story of a few episodes around the episode you quit on that almost made me drop it too ,but it's worth it to plow through) and also Sungkunkwan Scandal. It has a really interesting story if you can get past the fact that everyone in the school is completely blind to the face that she's 100% a girl.
