I went from thinking he's a goth, to an edgelord, to a sociopath hahaha. I'm glad I wasn't there. MC has a better poker face. We can't really ask him about his long history of manipulating others. Or, at least, I couldn't in my first route so far.
Some people say he's traumadumping for an hour. I think it's worse than that. It's an exercise in slowly cooking the frog to see when it might jump. He's acting like someone with no social skills: we know he's a skilled manipulator. It's a front. He knows exactly what buttons he's pressing. He WANTS a honest reaction after wearing us emotionally down.
All around, it felt less like a date than an interview to become a corpse. I didn't get to see what kind of yandere he is yet. Or what triggers him, though. It's definitely a horror game. I just don't understand how MC isn't deeply vary of him by the end of it. Maybe I didn't make enough choices to condemn his actions.
