Pretty bad adaptation of a decent novel, it removes practically all the world building and character development leaving just the tropes that 90% of the genre has and some of those aren't even done correctly. There is literally a scene where he bumps into another student, she drops her ID which he picks, and then she just, doesn't reappear, even though he meets her again in the next chapter in the novel.
Also, I don't get why people keep comparing this to Damn Reincarnation, no one forgot Hamel, the only thing that was changed about his story was that he was in love with Sienna and confessed while dying, he wasn't forgotten like Kyle.
3/10 adaptation of a 6.8/10 novel, still readable but not recommended.
