Childe is the prince's personal guard. He follows him on his duties and makes sure he has his needed supplies.

It's currently the day of the annual ball for the kingdom. However, instead of the prince and guard being at the ball, Childe is pinning the prince against a wall in a small office space.

Their lips meet, Childe's hands on the prince's waist. His feelings for the prince are clear. Knowing how the prince feels... well, that's a different game.
