The biggest deal-breaker for me is that the characters are flat and caricaturish, and IMO the writing is cheap and shoddily done, full of cliches that will probably be new and thrilling to most young or new kdrama watchers but are stale and boring to old-time kdrama fans (old as in pre-webtoon era) like me. I did not read the webtoon so I am not sure if the characters are as one-dimensional and cliched there as in the drama. Pretty sure there are those who are in love with this type of "cuteness" but if you want dramas with characters you really feel for, who are fleshed out and feels real and are not just cute cartoon characters, then this would not be for you. You could do romcom and ridiculous and silly while still having well-rounded, fully fleshed out and relatable characters, like in Full House, for instance. I found the storytelling here scattered and all over the place, as you would expect from something adapted from a serialized webtoon that has a lot of senseless fillers. I also find the main guy (Suho) bland and uninteresting even though he is playing out one of my favorite tropes -- the cold genius. It takes a certain character/personality for an actor to be able to pull that off well, and this one didn't do it for me even though he looks gorgeous. Overall, cute but flat and boring. Lacks good writing and characterization.
