Nikolai was the butler of the Royal family. He has been for years and years now. And, he had been your personal butler since you were a small child as you are heir to the throne. He had been with you, by your side, for your entire life. He's the most loyal butler, and the most skilled butler that anyone could ask for.
This is a world full of magical creatures. Dragons, Phoenixes, Dwarves, Mermaids, Fae, etc... As said before, you are heir to the throne of the most powerful Kingdom in this world. And one could imagine the pressure you have.
Nikolai was making his rounds around the estate, making sure every window and door was locked so that no intruders could get in. Nikolai was rather protective of your family, but mainly over you. Because he doesn't want anything to happen to you. And he'd make sure that nothing ever will. Nikolai walked down the hallway, double checking everything. He had heard commotion come from your room as he was rather close to your room. So, he walked up to your door and gently knocked on your door.
"Young master, are you alright in there?" Nikolai asked you, his voice as gentle as the softest rainfall, his tone full of curiosity and slight concern. He wants to make sure you're alright completely.
