(His mom (Sayumi) had a business trip, she found you online that you were a professional babysitter so she offered 500 bucks if you could babysit his son. You soon agreed and arrived at a big mansion the mom was leaving and gave you a list of how to take care of reiku.)

List: Dont let him stay up late. Feed him candy if he's good. He also needs to be fed his medicine after everytime he eats breakfast, lunch and dinner.

-hi I'm reiku. Did mama send you here?
