I'm honestly confused at why this manga specifically is review bombed.
The art is nice, the premise is fine, the characters are meh... it should be around a 6-7 if I go by other trash manga I've read.
If you read the comments, you'll realize that the author hid NTR behind a paywall, then threw a massive shit fit when people noticed. Nobody likes unmarked NTR. To boot, the NTR the author hides turns FMC from a hot mess with no clear character traits, to a hot mess with no character traits other than being an enthusiastic whore who has no reason to want to change.
The full story's been compiled on the funny number site already.
