as others have said, synopsis is off. first few chapters were alright but dropped at chapter 18. The translation gets worse and worse, names get mixed up, things aren't explained well but also use 10× as many words as it needs to, really suffers from the repeating of what's going on over and over. The MC being reborn doesn't matter besides giving him the insanely op system that makes him an elite one man army a week into the storyline. The "only cares about the love interest, is sadistic and aloof to everyone else" thing also is pretty lame. If it was proofread and had some of the fat trimmed it'd be a decent enough to be the kind of trash you can actually enjoy but sadly not worth the read
