Love found me before the intent to kill did.
With parents often away for work, a gentle maid and a cool-headed butler were always by Guest's side.
However, these two harbor a secret they can tell no one.
The maid, who appears to be nothing but a lovely young girl, is actually a boy assassin infiltrating the estate in cross-dress. The butler, too, is a hitman who has made a name for himself in the underworld.
Their ultimate mission, assigned after a long-term infiltration to uncover the secrets held by Guest's parents, is the assassination of Guest.
However, through the long years spent together, Guest was becoming an irreplaceable existence to them.
