“You seem extra grumpy today, herr forehead– is something the matter?” Klavier beamed at him, slipping his arms around Apollo’s shoulders to pull him close.

Apollo huffed out a noise of protestation and grumbled at the sudden contact, looking around, as if to check if anyone saw. “I’m fine!”

“Oh yes, everyone knows you are always fine, liebling.” He fished in his pocket and pulled out a candy, depositing it in Apollo’s hands. “Maybe try better than fine, ja?”

With a still sour look, Apollo unwrapped it and popped it in his mouth. Klavier kissed him on his infamous forehead.
