Bones and Petals

In a world where humans and vampires coexist, bloodthirsty Jess falls into a trap set by humans and is imprisoned in the basement of a slave camp. The camp's warden, Philip, experiments and tortures Jess in order to cure his genetic disease, but for some reason, Jess does not recover like other vampires. Philip stops the experiments and imprisons Jess with former doctor, Johan, in order to help Jess recover. Johan cannot leave the prison until Jess recovers. Eventually, he tries to open the wary Jess's heart, and in the process, Johan becomes increasingly fascinated by the mysterious vampire. Jess realizes that Johan likes him and pretends to accept his heart in order to use Johan to escape the dungeon... Will the two be able to escape this hell together? Will they really be able to return to their old lives once they escape?
