wasn't sure where else to ask, i came upon this untranslated manga in 2006ish, it may have been japanese or chinese, i'm not really sure, i don't remember much about the characters used in it.

the manga starts out with the main character being a punk and doing things that make him look like a delinquent. one of the chapter covers has him on a bike. there is a scene in the first volume of a girl using a very old japanese style toilet. it later evolves into him turning his life around and becoming a businessman or maybe even a politician. i used to have about 15 chapters on my hard drive, but i lost them a couple years ago in a format. any help would be amazing. wish i could explain more about it, but that's all i really remember at the moment.
