I mean most characters in manga have their touch of crazy and they don't fall into this category...
But maybe i believe this because the beat of the story when it started was different from when it ended. This is a typical story of obssesion to be special to your special one. Miscommunication big time that was fixed afterwards... that is all.
This was a really fun read + although not at all a comedy, was hilarious to me because at the start it's exactly what you'd expect for a dark twisted psychological BL, with an obsessive manipulative yandere etc main character (especially since we can see his POV, his thought process and intentions lol). However! They're both slightly off in ways that are perfect for each other, so once they figure everything out it actually turns out to be a pretty sweet, mutual + healthy relationship.
