The game has nice drawings and aesthetic, the music is really good. I'm no writer, but i couldn't quite undestand the reasons of the obsession of the main character, from the exploration of the house i got that he was an otaku and that's about it, i guess the mental illness was something like Dissociative identity disorder or something, but since i don't know much about the mc is hard to tell, i guess his love was also solely one sided, the brain was the best part of the game.
