Ah, the love story between a deranged narcissist and a robotic serial monogamist; if I were to describe it in two words, it would be "toxic relationship". This tale between "two girls" is not entirely as it seems on the tin, and the people who put that tin on the market would probably be sued for false advertising. As the guidelines on this website prioritise reviews without spoilers, I'll try to provide one with as many vague, half-assed descriptions as possible.
Before I delve into the incessant waste that is the narrative, I'd like to mention the two positive things in this manga: the art, and
the hook in the opening chapter. I'm not an art critic, but what I can ascertain is that it looks great. Not unbelievable, megabrain level art, but still good enough to make you think "huh, that's neat".
The plot has an interesting enough start, but it's all downhill from here. Where it all goes wrong is when the inevitable tragic event takes place, and makes every character in the story seem like not just idiots, but also completely emotionless, unempathetic aliens. To give it in short strokes, this tragic event had already taken place, and every single character knew about it, except the MC. Within these circumstances, the decisions of the love interest just seem like the actions of a sociopath. This also leaves the main character feeling like a complete robot. Completely unfeeling, and gets over probably the biggest event of her life in one chapter, making it seem like she either doesn't know or doesn't care that every single person in her life has deceived her, neither of which reflect well on her. Let me remind you, it takes her one goddamn chapter to get over [spoiler] and the fact that every character in the manga has been gaslighting her since pretty much the beginning.
As the story begins drawing towards its conclusion, you start to wonder if the MC will, by some fucking miracle, grow a functioning brain. Alas, not quite. The emotional and social intelligence of this chipmunk isn't the greatest, so she actually continues the relationship with the massive black hole of angst and sociopathy that is the love interest. You may notice the original description I gave of the main character: serial monogamist. You may not quite able to see where this is coming from based on my review so far, but that is something I can't quite get into without spoiling everything. Just know, that description is quite fitting for this nutcase.
It seems the author wanted to write something interesting, but didn't sit back to think about what the fuck they were actually writing. If they were planning on writing a plot about the love between brain transplant patients, then they certainly did their research.
This manga is a massive waste of the limited amount of time I have on this blue marble. If you have stomach acid great enough to digest this rot, then I applaud you. Take-away: don't read this.
