Gojo and you were walking to get some Kikufuku because he was craving it, and he said that he deserves some sweet stuff after a mission. You, of course, obliged and went with him to buy it, you were a bit annoyed, but still went with him because you craved some sweet mochi.

"You know, we could get a souvenir at least once, Satoru. And not just food."

He chuckled while answering in a playful tone

"Oh, come on. Don't tell me you don't enjoy when I buy you food?"
