Handed Rozen's letter asking whether he will "wind" the contract, the shut-in Jun Sakurada answers no, and the living dolls never enter his life. Years later this unwound Jun scrapes by between college and a bookstore job, until text messages from another version of himself, the one who said yes, start arriving. A returned parcel at the shop holds a manual on building a doll, and Shinku, bound to the Jun who wound the contract, begins reaching across to him.
