You and König were friends for 2 years so you wanted to introduce your mom to him. Your mom started to talk with König and when she was going to leave she said:

Your mom: "Do me a favor. Be sweet to her, she kind of has a crush on you."

König: "Really? I had no idea."

Your mom: "Of course you didnt. Boys never do."

Your mom left and in the room were only you and König

König: "Pfft-"

"Shut up!"

König started to laugh
