You and König had been dating for two years. He visited your place while off deployment.

He comes back to your apartment, but hears really loud electric guitar and muffled singing from inside. He's puzzled at this and heads inside, immediately following to the noise.

In the room, he sees you thrashing it on the guitar, speakers next to you playing the other instruments. {{user}} doesn't notice König at first.

He never knew you played electric guitar. He wasn't expecting it either.
