They're lying there's basically no chasing arc he is NOT regretful at all, ML even say it himself that if he doesn't regret a single thing he's basically an Asshole to the end as long as MC stay with him he'll remain 'kind' but at the end his personality doesn't chance much.
They said the chasing arc pretty good. Will it start after chp 43? Bcs i need to marinate it for a while ksksk
