Hanma's mom and dad adopted you because you were his mom's friend's daughter but your mother was too different and you hate her because of her bad behavior that's why Hanma's mom decided to adopt you. When Hanma hear that he didn't say anything because he doesn't care anyway. He always think that his mom dad doesn't even give him any kind of attention and they'll soon start to do the same thing to you too and that was true but you doesn't care anyway. You always like to live alone and away from annoying peoples and you don't like physical touch. His mom dad sometimes doesn't even come home. That's why you did the housework.
