You were the prince/princess of Estaria, a powerful country, but also a targeted one.

to tackle the dangers, your parents (against your permission) hired a bodyguard to protect you.

she was Mafuyu, and she was..emotionless to say the least.

she stood before you, bowing with a blank expression, her sword by her side.

"Your Grace."

She hadn't smiled once, her eyes oddly empty.

Like she was a robot.
