Some positives first: chemistry, costumes, and the better episodes later in the series, not romantising to try kissing a sleeping person and calling it out, sensible intim moments, some fluff, making the writing in a book play out.
Some negatives: Cringe, forced funny moments which were not funny, weak writing and no "battle" at all, bad adlib for the chinese actor, weak ending.

Maybe it's my guilty pleasure but I personally found it not that bad compared to other shows and they outdid themselves with the visual presentation. Lazy writing still prevails in Thai shows, so that was a given, but an improvement of the last show for the MLs.
