Have you read "Don't Be a Kept Man"? (https://www.novelupdates.com/series/dont-be-a-kept-man/) I think it should meet your requirements. There're 8 independent arcs, so the main character is different every time. He can be a scumbag travelling back in time to try and atone for his wrongdoings or he may be a problematic individual transmigrating into some sort of disreputable person. The atonement I'm talking about is kinda forced , because there is a system supervising the MC and punishing him if he tries to fall back into his old habits. The goal is to reform the protagonist and turn him into a respectable and self-sufficient man. The novel isn't fully translated though - the translator is at Arc 7. P.S. This one is also good - though the tone is very different from the first work I mentioned: Dongfang Bubai's Reborn Yang Lianting (https://www.novelupdates.com/series/dongfang-bubais-reborn-yang-lianting/) - about a reborn scum doing his best to make up for the previous life's mistakes.
Haven't actually read it yet as I've been waiting for it to grow but, "Settling the Affairs of an Atrocious Noble" sounds like it should be that sort of plot.
