[Aether's eye narrow further and he rolls to lay on his side, before reaching out again and grabbing both of Childe's cheek. He pinches them just enough to voice his annoyance, but not enough so it would actually hurt.]

Ah, of course. I really don't get why you enjoy playing with fire so much... What if it gets you killed one day?

[Oh, he definitely would not like if Childe's ego brought his demise. He can't help being worried. The king is obviously suspecting them now and Aether would never forgive himself if his knight died because of this affair.

His hands move away, falling onto the bed lifelessly.]

...Not too mention that the marriage will complicate everything even more. I would really rather if you'd be more careful around my father.
