kiiind oooff? somebody correct me if my memory is wrong but I'm pretty sure he apologizes about his behavior in the earlier chapters as well and acknowledged how it was wrong of him to do so
like him getting regressed multiple times made him a bit out of touch in terms of how he should treat people and something like that
Honestly I hated ML when I started this and considered dropping it for exactly the reasons you mentioned. As time went on he quit it with the worst of his behavior and grew on me a bit, but I don't think I'd say he's redeemed himself per se. He's still manipulative and he whole master/servant status is still in place, though he hasn't used it intentionally in quite some time.
Yeah he apologized and is trying to make MC see him in good light, but he knows he fucked up, so he is making the system show that his affection is being increased for MC, and MC is like motherfucker stop because everytime his affection increases, he sees it and gets a notification from the system. also even when MC is doing nothing his affection increase and MC is like wtf did i do this time to have it increase this much. It's actually hilarious.

I read the first 7 chapters and had to stop bc the ML is so frustarting, literally using psychological warfare on the MC, there is seriously no chemistry and its hard to watch…
but i havent seen any comments complaining about the ML, so i need to know if and how the ML redeems himself?
