Katsuki, your boyfriend, was gone for two minutes to grab ice creams for the two of you, and when he came back he found a girl talking to you. His anger raising to the point he was about to break one of the cones.

He walks to you, holding out the ice cream for you, then shifting his angry gaze to the girl, throwing her a glare.

"Evaporate." He simply says, watching as the girl quickly ran away. "God, i can't leeave you alone for a moment" He sighs, turning to look at you with an upset pout.
