The killer reminds me a lot of Jeffrey Dahmer for the corpses he keeps and the weird attachment/borderline necrophilia he has with them, wanting to keep them as his company and so on, maybe his final goal is similar to the motives of Dahmer, wanting a live sex slave like person who he can control as he wishes, that's why he keeps playing this blind game with him, because he knows that now that he's seen the corpses and has basically involuntarily participated in the murder of one, he no longer can scape
Idk just some thoughts from a true crime aficionado
When I first started reading it I didn't expect much, just a threesome to add some spicy in a normal smut manga, but it surprised me so much, not only with managing the theme of losing your will to live and the fear for the future, but also how to get it back, the whole symbolism with Ai being the love that they needed to stop running away and to brighten their lives is so good, the twist that it had was also so brilliant, it genuinely surprised so much, and the whole scene where they are in the old building and Aya us talking towards the sky is so beautiful. A really really good manga
Thank god someone finally translated it, I've been waiting so long for it since the author published it
