Not on your list:
Surprisingly Only for Love only got an 8, I gave it a 9. It's has domineering CEO troupe, pretty fun. It should be quite mainstream though since both lead actors have huge fanbase.
Best Choice Ever is a female empowerment drama, the lead actress' speciality these days. Should also be quite mainstream.
Unrequited Love has this slow-paced plot that I find comforting, suitable to watch in between fast-paced complex thrilling drama.
Justifiable Defense may not for everyone, but it delve deeper into humanity, the fine line between justifiable defense, excessive defense, and intentional murder, and how one's reaction under any circumstances is the most important thing that could change your situation. Interesting yet saddening, imo.
