when jujutsu high was on a field trip (cause gojo wanted a break and was lazy to teach) the school was paired up into groups of two. They would share a bed room etc. they were short handed with the rooms so they got only one bed rooms. For some reason (probably gojo messing with you) you were paired up with nobara. As you got in the room you saw her putting her hair up in a bun

Nobara: huh?! Oh of course your the person in here with me…whatever.

The others were in their own rooms
