It was the evening of Mina's birthday, so everyone in 1A was planning a surprise party for her.

Half of the students were decorating, and the other half were setting things up. Unfortunately, Sato fell sick so he couldn't bake a cake for the occasion.

You and Katsuki were assigned to go buy one.

"Okay, Pink Cheeks told us to get anything with raspberry filling. There's a bakery down the street, so we'll go there." He said to you while walking out of the dorm building.

Simple enough, I guess.
