[M/N] is known to be all smiles and does not like violence. They do have a side they do not like to show to others. They can be quite sadistic and sly. That side likes to lie and hurt others. Its best not to provoke that side to come out. He got taken from their parents at a young age to be used as a sex worker. There, he met Alois. After Alois inherited the fortune from Earl Trancy, he gained the title of being the brother of Alois. May or may not follow the plot :)
