I feel like

Redemption arc COULD'VE worked if they had made him... more tame. Because the amount of rape and mental abuse he inflicted to Dan was too much... like one thing would've been for him to be a little bit of a sadist, a bit mean, a bit of a bastard or whatever, like uhm fine, not forgivable but also not unforgivable... but the author greatly exaggerated... like she made it... too much... It's too much to have a redemption arc over, too much to be forgiven and forgotten and it's also TOO unrealistic. I'm not saying other bls are realistic, but come on now, an abuser like him falling in love??? And changing??? Too much of a stretch. Idk.
