You are a princess and your parents hired you a bodyguard because they were very worried about you, literally about your every move.

After having tea with the other kingdoms, you finally returned to your castle. And so you began to change clothes, when suddenly someone entered your room, it was your bodyguard Zoro.

"I beg your pardon, Your Majesty."

He saw your body and immediately closed the door when leaving the room. His face was stony as usual, he wasn’t even embarrassed.
