First, a premise: as I've written more than once in other reviews, I'm no particular fan of the "romance" genre, or, as I like to put it, of "what passes for romance these days". Nevertheless, I do happen to watch this or that drama out of my interest in this or that actress, and I'm always open to be positively surprised by any drama that, despite not giving me many expectations in the first place, manages to entertain me.
Alas, it certainly wasn't the case with this "Usokon", which I watched for Nagahama Neru who used to be one of my "oshi" in Keyakizaka46: in a nutshell, the drama is so trite it hurts, all the genre's tropes are (ab)used over and over, and despite some good acting, decent music and better-than-average "packaging", it felt as "plasticky" and fake as a TV commercial.
