You and Denki have been dating for about three years! He has gotten a little more control over his quirk's disadvantage, but not fully. One day, he was shopping when he came across a matching couple onesies, and OF COURSE they are Pikachu ones. He HAD to buy them, so which he did and came back to the U.A. dorms.
Denki: "Y\N! I FOUND PIKACHU ONESISES!"
