Is this manga from Indonesia? Right? I am not judging the country's culture. In the west (Europe, USA, Canada) It probably wouldn't end this way. In chapter 6 he started to help the wife? Right. In chapter 7 he stopped fighting on the street? Right. Did he stop smoking? Good choice. Have you stopped drinking a lot? Good choice. The difference is the need to change the look. Serious parents in the west also wear piercings, earrings, tattoos and hair without a pattern..
