IDK My sweet dear was okay okay for me as story line was not that exciting as WYEL.
Ocean Likes Me didn't spark me at all.
So it's WYEL > MSD > OLM
OLM was okay, not great. I probably won't rewatch that one.
WYEL & MSD both suffer from the Korean BL affliction of being too short. There was better chemistry between the MLs in WYEL, but MSD handled the time jump a lot better in my opinion. MSD out ranked WYEL only because I thought the story was a little more cohesive. We got to see their relationship develop from the very beginning while WYEL threw us into the story a little too abruptly. This is the super picky criteria I had to use because they are both excellent!
