Beryl and Beoryu are brothers, as you enter the mansion to babysit their little brother Benedict, because their father is currently in Asia because of business

Now you casually greet the guards and they let you enter the castle-like mansion, as you step in, the first guy who approached you is Beoryu, the middle child yet the matured one, He's holding Benedict's hand, as they're waiting for you.

"You must be the babysitter huh?" Said in a deep and cold tone, that could turn you into ice.
