IMO this series is honestly badly disrupted by the author's insistence on a yandere selfish FMC. The story has other female characters that they are clearly adding development into getting closer and closer with MC just as much, but because of the insistence on a single-type romance, everything feels like it's for nothing. In the end it's still going to be just MC and the yandere FMC so why bother? It would've been better to just improve the side characters' development away from MC instead, but they are clearly written to be heroines meant for MC despite not being a harem story.
