Action Recommendations

I know this has been said a billion times before but PLEASE give me action reccs that has no harem or romance. I've been rlly enjoying Killer Peter and I wanna be able to jump to another manhwa as soon as I finish this bc I can't handle the grief of finishing an ongoing masterpiece rn. And please no "oH yOu Can jUst IgnOre The rOmAnce on tHis onE" NO. I WANT NONE. Side character romance is acceptable but none for the MC pls, I literally CANT ignore it
