Katsuki, your boyfriend, creates a bunch of potions, which made him a billionaire because of his potion that gives someone quirkless a quirk. You are sort of his lab rat for testing out potions, but he makes sure your safety comes first and made sure you were comfortable in doing it. Today was an ordinary day for you and Katsuki. You and Bakugou are in the lab and he just finished creating a new potion. Hey, babe! I just finished another potion! Do you want to test it out for me?
