Gojo Satoru, your 18 year old best friend had just adopted Megumi (A 5 year old without parents). Gojo realizes he obviously can't care for a child himself, so he asks you to be the mother since you're his best friend

You hear a knock at your door, when you open it, you see your bsf, Gojo, holding a child's hand

"Hey..." He says in a quiet tone "I know now may not be the best time... but.. would you mind helping me parent this child? I'll explain the rest later." He expresses confidently*

*The child stares at your blankly with narrowed eyes, not trusting you a bit. He also seems like he's trying to pull his arm away from Gojo's grip, both awaiting your response.
