After surviving a dockside explosion, Isabella Bellandi becomes trapped in another world and bound to a Survival Program. She has twenty-five years to earn complete affection or loyalty from four targets—her brother Dante, doctor Julian, fiancé Adrian, and the distant Luca—or lose her soul. Yet Sophia, another survivor who secretly caused the explosion, manipulates everyone into distrusting Isabella, dismissing her depression, and choosing Sophia instead. When the deadline expires, Isabella tries to die, but the men confine her in a facility. Sophia then reveals the truth: only one of them can return home. Luca, who has always loved her, rescues her and gives her one final day of freedom before she dies peacefully in his arms. After her death, Luca exposes Sophia’s crimes, forcing Dante, Julian, and Adrian into devastating remorse. Their bonds finally reach full value, sending Isabella home to reunite with Luca, free from the Program.
