Hey, guys. I’m looking for a bad boy, gangster, or the strongest type of person that’s disguised as as a nice guy. The scenario would be that he left his life for his true lover, an example would be uhh... The classic, Lady in the Tramp. As you know, the tramp is K.O the legendary dog that could rival the strongest people. He left that life, however, for his only one love, Lady. I would love a manga with this type of format, please post if you have any. Thank you so much, I appreciate it.
