The ending was rushed and the relationship wasn't explained enough. What I mean by explained is, he went from seeing M as a child, little brother, someone he wanted to take care of into his lover? That's just mad ick and predatory. And it feels like any explanation was just glossed over. And it made it worse every time it showed M in the likeness of a baby or a child, even though he was an adult. It also didn't give me the satisfaction of seeing that horrible mother crumble. I also didn't like the art style.
