I've seen a lot of hate comments about this manga and I just want to say they're all correct.
To describe this manga in one word, it's "half-assed". In one phrase, "a waste of time". It starts off as a coming-of-age story focusing on a self-depreciating character that will relate to many, but do not let the first 10 chapters fool you. Nothing that happens in this manga matters.
Every substantial development gets dropped half-way through. Like, I mean it. If you're lucky, some characters and plot lines will reappear later, only to regress to when they first started out, receive some bland backstory and superficial growth out of nowhere just for the sake of making more chapters. Others will just straight up be forgotten. The abhorrent pacing does not do this manga any justice, either. Actually, you know how when you're listening to some intense music and start imagining your OC(s) doing epic stuff? Yeah, it's like that. Now put that idea to pen and paper and the result will be this manga. Neat concept, horrible everything else. No offense if you're a maestro at writing fan-fiction, of course.
The problem, simply put, is that all of this is just that - a collection of good concepts. The ending is merely a symptom of this problem. This manga has no depth, no flow, and makes no goddamn sense. It tries to take on wayyyy too many issues, only to excels at nothing. Competent at nothing. I really just wanted to say oh haha this is such a trash harem but no it's genuiely a frustrating piece of art. I was bored out of my mind reading the last 1/3rd of the manga, so much that I'm ashamed to say that I unironically kinda see the appeal of TikTok videos putting those split-screen Subway Surfer clips to retain viewers' attention. This manga does not respect your time, so don't give it that.
As always a massive thank you to all the scanlation groups for their hard work translating this manga!
