The only other one I can think of off the top of my head it is technically a romance but, barely and that was this one
https://www.mangago.me/read-manga/mercenary_enrollment/ I wouldn’t say the mc is exactly evil but he definitely isn’t like a pushover, he goes back to do his old work but only when HE wants to. Anyway im not sure if these are the kind of recs you’re looking for but I hope if you check them out you like it!

Evil mc recommendations?? Not evil but like not a pushover and kinda selfish like estate developer or the demon king farming
