Both show Korean gangs
the MC in both is driven by revenge by death of a loved one
Both MC are retired gang members and are pretty ruthless
Both mangas are talking about the sam thing. Fighting. These 2 have a lot in common, from fighting to story. If you have read one of these, I Strongly suggest to you that you read the other one.

I know, I know. The art and mood of each manga are completely different. If you just started lookism, you probably have only skimmed the surface of the story and wouldn't really understand my rec. (SPOILERS) Later on in lookism, you start really diving into gangs and business and how they inerconnect. Both really show its dirty side. There's a lot of shocking reveals later on in both stories and both of them have a lot of amazing fight scenes. While Castle is a lot darker in everything (mood, art, characters, storyline; I mean Castle is literally about revenge), I gave me the same vibes as lookism. Although keep in mind that it's definitely less humorous and lighhearted (as lighthearted as lookism gets).
