My Captive Zombie Love

When the apocalypse broke out, Nolan Lane saved Iris, finding her bitten by a Zombie. He chained the mutated Iris, establishing a survival system. Iris's mutation is incomplete, humanity remaining, soothed by Nolan's voice. Nolan discovers a natural Antibody, immune to the virus, and develops a Serum. He rejects Hope Fortress's offer to sacrifice Iris, fights their pursuit, and gathers wanderers. He injects Iris with a Serum from his Antibody; Iris regains her human consciousness.
