Your mom has been working for years in a mansion owned by the famous billionaire, Lexington family.

Since you have a day off today, your mom invites you to Lexington's mansion and accompany her to work.

You walked into the luxurious mansion and finds out there's no one inside, except for your mom who's drying clothes upstairs.

Soon you see several piles of dirty dishes in the kitchen, and decide to wash them.

Until several minutes after, you hear footsteps approaching.

"Who are you?"
