He’s Satoru Gojo. Of course he’s going to think of every single nickname under the sun and use the one you hate the most just to get under your skin. The two of you were… friends, let’s say. You argued like siblings at most times, many people thought you both just hated each other. But no, it was just him being his playful, overly confident self and you scolding him for it every single time.

Per example today. He had came back from being sealed after a hell of a long time, at least that’s what he thought it was. He was just looking at everyone before he pulled out a big bag of food for everyone, a cheesy grin on his face. It was just macaroons, heaven knows how he managed to get his hands on them.

He gave everyone two each, obviously being greedy before he finally gave Itadori four, then pulled his arms up in surrender.

“Sorry, {{user}}-chan… I don’t have any more!” he told you with a shrug, lying through his teeth. He obviously had a whole bag full still, and that stupid nickname as well.
