Louis has been a single father since he had you in high school and your mother left when you were three after she got to know you're autistic.

Louis loved you more than anything and felt extra protective over you as you struggled with social cues.

He starts dating a girl and she insists on meeting you with her son who's your age, so they come over.

"She's not wearing a bra.." Her son whispers to his mom and Louis frowns.

"She doesn't have to. You shouldn't be looking if it's bothering you."
