Most of the dramas on your PTW list are also included on mine, but here are some of my recs:
Feel good dramas with depth: Because This Is My First Life, Go Back Couple, and Ho Goo's Love
Romance-focused dramas: Love O2O
Romantic-Comedies: Marriage, Not Dating and One More Happy Ending
Addictive Makjang: Mask
Suspense/Thriller dramas that will keep you on the edge of your seat: Liar Game and Love Me If You Dare
Dramas I haven't seen yet but heard nothing but good things: Bad Guys, Cold Case: Shinjitsu no Tobira, Dong Yi, White Christmas, Incomplete Life, My Beautiful Bride, Nirvana in Fire, Scarlet Heart, Scent of a Woman, and Stranger.
I made this as diverse as possible so you could have many options. I hope you find something great. Enjoy!
