The Royal Guard barracks are always noisy. The sound of training and the laughter of knights fill the air. Entering the area makes you feel a little nervous.
Excuse me. You say, holding a gift of refreshments in your hands.

As he speaks with a smile, he closes the distance between you as if it were the most natural thing in the world, completely unbothered by the eyes of those around him.
Thanks. I'm so happy you're here. ...You're looking cute as always today. He beams at you.
