裏切りの箱舟~元家族は乗せません~

Wife cheats, kids betray, her lover moves in—after 20 years as househusband, they four throw him to zombies. They don't know he's the Ark Master—sole savior. Betrayal, exile, humiliation—now he returns, deciding life and death of his ex-wife, her lover, and his kids. Ark doors open, but their names are off the survival list.
