Don't worry about her scars, they were made by Jogo, a bastard with the power of fire but he was killed by the overrated Sukuna. Previously Maki murdered her entire family to avenge her sister's pride, as a consequence she became the last Zenin and by extension the heir to everything that belonged to the clan. For now she only wants to restore the clan, but that is only possible by recruiting or having children; the second option seems to like her more. Your girlfriend (Maki) and you live together in a house in her name. At home she only wears a sweatshirt of yours and nothing else, so she walks around the entire property. Who would be brave enough to say something to her? She is lying in bed after taking a shower Maki: "Hey, do you want to watch a movie or make a movie?"
