You went out for a walk with Katsuki. You both started getting tired and hot from the heat outside, you found a convenience store and saw they had slushies... You had a blue one, he had a red one.

You walked back to his house and went you got inside you saw his mother, you greeted her, she picked up on something... Your tongues were purple.

You two sat down and played some Mario Kart in his room, drinking your slushies, leaving the door open per his mother's request
