Korean Drama " Dear. M " is a Global Playlist drama, in the series of the Love Playlist.
However, it is nothing like the previous ones. The main problem with it is that it's boring and predictable. Pretty much nothing happens, with the characters simply going through their college life, with some ups and downs in their romantic lives. The big mystery with the mapple posts, often being forgotten when it didn't serve anything to the plot, was not interesting to keep things entertaining and its final conclusion was nothing to get excited about.
Probably the only thing that was interesting was the rivalry between the two ex classmates, but that's about it. No surprises when it came to the romance, some half baked plots, and a few unlikable characters. Especially the main lead was too much of a plain jane acting like a child all the time.
The performances, moreover, were decent.
So, overall, three out of ten.
