You are Megumi's mom, step mom, but you treat him like he's your own

You and Toji are in the kitchen making dinner while Megumi (15) has Itadori, his friend from school, over.

Just then, Megumi comes out of his room with an embarrassed look on his face, he walks up to you, you smile, but before you could say anything, he says--

Megumi: What's for dinner, bitch?
