System Husband: One Divorce and I'm Gone

Alan has stood by his wife Charlotte Cooke for ten years, ever since a companion system brought him into her world. His task was simple: remain married to her for a decade, and he would earn the right to stay. But Charlotte's attention has drifted to a young man named Bradley Bell, and when Bradley demands something official, she rushes home to ask Alan for a fake divorce, promising they will remarry in seven days.

Alan agrees and signs the papers, though he knows what she does not: once they are divorced and living apart, the system will declare his task failed, and in seven days he will vanish from this world forever. Charlotte showers him with parting gifts and hurries him out of the villa, while Bradley waits to take his place.

As Alan checks into a hotel for his final week, billboards across the city celebrate Bradley's birthday, signed with Charlotte's own nickname. At the Cooke residence, her father Jordan Cooke rages that Alan is the only son-in-law he will ever accept.
