This is... an incredibly dissapointing ending. Dissapointing in the fact that it went too fast. It all feels kind of sudden. You're telling me these guys are experiencing schizophrenic-like behavior throughout the entire manga, and then they all just solve their problems in a couple of chapters?
There's also so many things unknown. How is switching bodies even possible to begin with? Why did she forgive that guy who I don't remember the name of when he tried to basically commit murder? What about the fact that the two girls are literally psychopaths? How am I supposed to be happy for them if deep down I know they're literally batshit crazy?
I say it's dissapointing because I like this manga. It was really intriguing to read the dynamic between the 4 main characters. Side characters could've maybe got more screentime but I think they did their job well.
Although I can see the argument that it is better off vague on purpose. It's very symbolic in the way it presents itself, and I don't think we're supposed to know all the details anyway. My main complaint is it just kinda ended way too quickly, like I didn't even REALIZE that we were wrapping up the story until this chapter.
