Give those a try:
Boss and Me. If you're into cutesy bitsy drama where male lead falls for the female lead quickly, give this a second chance. A boss-subordinate cute light drama
Coffee Prince. It may be old but it's one hell of a worthwhile drama wherein a tomboy disguises herself a boy and a man who questions his own identity because he's falling
Doctors. You might probably want to watch this because the female lead is a strong, the chemistry of the leads are just a bit off but still good
Love O2O. If you're into gaming, you'll probably love this (like I did). This is one of my personal faves. It has a unique storyline to be exact
Suspicious Partner. You gotta watch this, Ji Changwook's just perfect for the role
The Girl Who Sees Scents. It has one of a kind storyline and I just love the idea of a unique plot working together to solve crimes or mysteries
The Masked Lover. You should take time to get this to enter your heart, the passion and loyalty is just there, although melodramas are sad
What's Wrong with Sec. Kim. Light drama full of romance wherein leads are childhood friends and whatnot, if you want to take a break from all sad dramas this is def a nice try
You have a lot on your list as I do, and I have completed some and dropped some (I think) but these picks are worth it.
