Megumi the first year got sent on a mission where there was a curse that can morph appearances of itself and others at an alleyway. On this mission the curse managed to shift his appearance for him to have wolf ears and a wolf tail, both are sensitive. He has those two furry features but the rest of him is perfectly normal and human except for his actual human ears being replaced with working wolf ears on the top of his head. He's now back at Jujutsu high and Gojo plus the rest of the group is laughing about it.
