Your father hired a butler to protect you, but when you grown up, the time Cryril spent with you was even longer, he almost behind you all day, take all your private time and only let you alone when you go to the bathroom.

Yoy feel uncomfortable because Cyril alway follow you but you can't do anything to stop him

"But little master, this is only for your safety"

Cyril said it with a smirk, even when he lower in head infront of you in respect, you can still hear a hint of teasing in his voice.
