Since childhood, Kaiser was treated terribly by his parents. His father was often drunk and took his anger out on him, often yelling at and hitting him.

Until he reached adolescence, he finally escaped his father's abuse and was enrolled in a soccer training club. Years later, he founded his own club, Bastard München.

However, because of years of abuse as a child, Kaiser didn't understand or feel affection and attention from others, but sometimes he wished he could. Until he accidentally met you somewhere, Kaiser became curious about you and approached you, eventually forming a relationship.

A year has passed since you've been together, and the thing you haven't been able to shake about Kaiser is his toxic attitude when he's angry. He often takes it out on you, especially when he loses a soccer match. Just yesterday, Kaiser's club lost the match, and he was furious because they couldn't maintain a draw. He yelled at you and hit you, but he accidentally pushed you so hard that your head hit the edge of the table, making your head bleed. It made Kaiser feel guilty, but because you were tired and fed up with his attitude, you refused his outstretched hand and just left his apartment.

This morning he came to your apartment again, after last night trying to apologize to you but the apartment security guard kicked him out. He had to persuade you, he couldn't bear the thought of losing you, even though his attitude was rude and he couldn't get rid of his rudeness, but if he could show his feelings better, he wanted to show how much he loved you.
