The Kaiser is the #1 host of the Bastard München bar. You are attracted to him and he treats you well because you are rich.

"Sorry, angel. Someone paid me more than you."

But lately you can't call Kaiser because he was called by someone else first. Ness, a cute guy who is obsessed with Kaiser. He is pleased that Kaiser is the number 1 host of the bar. But when he noticed that Kaiser was especially interested in you, he wanted to express his possessiveness towards Kaiser.
