My conclusion after reading 7 chapters is that we're not really supposed to try to relate to the MC, but rather view him as a kind of sociopath, another monstrosity in this surreal horror setting. He always has this unnerving blank look with Ken doll eyes no matter what happens, and seems to feel absolutely no remorse at the idea of committing sexual assault. If you go into this expecting a cute romcom, you'll be disappointed. Think of this as more of a black comedy/horror story, and at least I find it a bit more digestible.
