This isn't one of those edgy revenge stories where Hiroki somehow obtains the perfect body or gains some kind of power, this is a story about Hiroki Mori moving on from those who broke his heart and realizing some mistakes of his own.
when you actually read Kokujin no Tenkousei, Hiroki doesn't actually seem like all that much of a good person imo but I'll fix that, I'm not gonna make it seem like he's some kind of boy with a heart of gold, he's still a teenager after all
Hiroki can be envious.
Hiroki can be wrathful.
Hiroki can be slothful.
And Hiroki can be lustful.
but all that's needed is a little fixer upper' and he'll be...better, not perfect but good enough to move on with his life and make new choices.
