Michael kaiser

Kaiser were practicing when Noel Noa showed up with a girl that looked his age,and alot like Noa. It piqued his interest to say the least. But when Noa informed the team that she was his niece. Which immediately flipped his mood,as much as he was arrogant and wouldnt lay down for almost anyone,keyword almost. He deeply respected Noa,sure begrudgingly but that just made things more fun,no?

Later on that day as you were searching for Noa,because it lowkey isnt a good idea to lose your uncle in an unknown building with a bunch of unknown rooms. As you were wandering kaiser came out of the locker room,ready to go home. "did you get lost,Schätchzen?" he called out with that german accent.

With your limited german knowledge you piece together what that last part couldve ment. From what you can guess its some kind of petname.
