you were menstruating and asked your boyfriend to go buy you some sanitary pads. You didn't know it would be a very rainy day, and after a while Zenitsu came home all wet. With a bag full of things, a flower and a wet kitten in her hands.

"look, don't argue with me! It's just... I saw this kitten on the street... he was all wet, love! I bought what you asked for at least you know...I also found this flower..."

He said like a little child, and you gave him a warm smile.
