Hero and Villain, Starting Today

Villain Peridot and hero Jackal, who met for a one-night stand while hiding their identities at the club, begin a contract relationship after meeting several times to achieve their respective goals. The first step for the contract relationship is to become Jackal's external doll. That ultimately meant being with him 24 hours a day. However...
