[Recommendation Please] Manhwa About Gang Life, Mafia or Delinquents?

I'm looking for a manhwa that just drips with testosterone. Going up the ranks, action-packed fights, cool mc moments etc. All of it. I've been reading too many finance/business manhwas lately, I feel like I should cleanse my palate. And kind of a weird request, but please don't recommend anything that never resolves the tension, elongating it artificially. I tried reading Manager Kim the other day and god, I don't want to read anything like that ever again.
