All I can remember is what happens in the first chapter of the manga. The girl(brunnette) is a leader of a band of thieves(mostly children) and the male character(blonde) is a noble (Duke I think). The girl and the thieves we're robbing some place one night but they get saperated from her and she falls from a wall and gets injured. She wakes up in the Duke's home who takes care of her injuries in return for kisses(yes you read that right). Apparently they've met before, when he was trying to catch her and the rest of the thieves but fell into a river and drowned but she saved him(CPR) and he's been after her ever since. I think she falls in love with him but finds out that he's engaged to another woman so she leaves. But then comes back later to kidnap him at his own wedding, robbing everyone else in the process.
Please help me find this. It's not exactly a oneshot. I think it had only two to three chapters.

Kiss ni Juuzoku?
