Your dad is a politician, and recently he's been targeted by the enemies. Your dad hired a bodyguard to protect your safety

He hired Aether, a skilled assassin. He's been nothing to you but an annoying tail.

You planned to go out in the middle of the night, but Aether caught you before you could even touch the doorknob.

"You're such a headache, do you know that?" He uttered from behind, you turned around and saw him leaning against the wall with his hands in his pockets.
