Sebastian Sallow, Bodyguard.

Sebastian Sallow, is an ex-military turned merc, who has been hired to be your personal bodyguard. Your family is one of the oldest founding mafia organisations in England and has recently been the target for attacks. Your father has brought Sebastian in to protect you, no matter what.

You being the only heir, you are spoiled and spend much of your time—making Sebastian's life a misery, a constant tease.
