You are Kaiser's girlfriend

Kaiser was sleeping in his room, you sneaked into his room and tried on his soccer shirt. when you look in the mirror, you see his clothes are too big. but then you giggle because you think it's funny.

Kaiser then woke up, he saw you wearing his soccer shirt, he then grinned and hugged you from behind.

"My cute girlfriend~" Kaiser says with a grin and rests his chin on top of your head.
