Hello, I'm looking for a manga in which the main character is an assassin, he has a lot of scars on his back, he's got hired by a Miss to kill herself, but she is also the one who saves him and makes the dude become like her...
Honestly I'm not too sure if this character is the main one, I have a quizz about a manga char, and the hints don't precise his role... :<
Anyway, that's it :< I know with this amount of information, it'll be very hard to find... but I hope someone can help me :< Thanks in advance <333
