There was for sure some kind of black magic used in the making of this drama. I disliked most everything about it (from the acting, to the plot, characters and music), and still, I found myself binging the whole thing.

Yoo Chan had the emotional intelligence of a rock and was pretty much a walking red flag. He always resorted to emotionally and verbally bullying those around him, and especially the FL. The fact that he pretty much only dated one girl during the whole drama, and she wasn't the FL has to be one of the oddest things I've seen in any romance, ever.

Bo Ra being nicknamed "idiot" by Yoo Chan was mean, but also highly accurate. She had a good heart, but often behaved in moronic ways.

The OST was a cheese fest and I'm happy I'll never have to listen to those songs again. Or the clicking of soles over those unusually loud floors! Never had I come across a show with floors as loud as the ones here.

The prosopagnosia played no role at all, aside from creating an insignificant amount of silly drama and was magically resolved, almost as an afterthought.

The drama was half the ML getting over his unresolved feelings over the disappearance of his first love, and half IT/business mumbo-jumbo with some out-of-nowhere, utterly out-of-character betrayal to spice things up.

Honestly, the only character whose story I enjoyed was Do Jin. He was the most fun and interesting.
