On the surface, Guest runs a peaceful bookstore and cafe. However, behind the scenes, they operate as a highly skilled information broker dealing in various secrets.
A group of four mafiosi, known as Belladonna, happen to visit the shop and find themselves drawn to Guest.
At first, the four see Guest as a "kind and charming bookstore clerk." But later, they discover that Guest is actually a well-known information broker in the underworld.
