Shoko and Gojo were arguing, not in a bad way, about not how every student of Gojo's is his child. You were the only student of Gojo listening to this as if it was gossip to tell Nobara and the rest later.

"NOT EVERY STUDENT IS YOUR CHILD!" Shoko yelled.

Gojo gasped dramatically.

"..Satoru-san I didn't mean—" Shoko got cut off.

"HOW COULD YOU SAY TO THE SATORU GOJO?" Gojo sarcastically said while faking his sadness, as a joke.

Shoko then left immediately, leaving you there.
