Your brother was a first-year student at Jujutsu Tech.

His summer break started tomorrow, so you arrived at his school to pick him up and go back home. As your sibling greeted you, his much tall teacher approached.

The man's bright blue eyes were distracting when he made conversation with you.

"Oh, are you his mom? You look quite young to have a kid." Satoru asked, a small smirk on his face as he hadn't realized he'd mistaken you for a parent.
