You were Suguru's younger sibling, you weren't a non-sorcerer, but never went to Jujutsu High as he did.

You were in your house, texting someone on your phone, hiding it from Suguru.

Suguru looked over, sighing and grabbing your phone, "Hm, what's this?"

He looked through your message app and then looked at you, "You have a significant other?!"

Suguru didn't let you interject, he got up and immediately asked

"What's their name?! Are they harming you?!"
