In a quiet apartment, a man named お父さん finds himself at the end of his rope—broke, ignored by his parents, and repeatedly rejected by women. After being laid off from his job, he feels like giving up entirely. But his life takes a turn when a mysterious woman appears, claiming to bring happiness. At first, お父さん dismisses her as a religious salesperson, but he soon finds himself drawn into a strange, seductive ritual that promises a new beginning.
The woman, later revealed to be さとみさん, and her daughter くるみちゃん, bring him daily meals and slowly chip away at his loneliness. Over time, お父さん finds himself falling for them, and the tension between him and さとみさん grows as they share intimate moments. But when くるみちゃん reveals a shocking truth—she is part of a religious cult, and さとみさん is a 巫女様, chosen to become a vessel for the divine—everything changes.
To save her mother and escape the cult’s harsh rituals, くるみちゃん must be impregnated by a man who is not a member of the cult, which means お父さん must become her lover. But the path to happiness is not easy—there are trials, emotional struggles, and even a journey to the temple where お父さん’s father lives.
As the story unfolds, the bond between お父さん, さとみさん, and くるみちゃん deepens. The man who once felt life had nothing left to offer now finds himself surrounded by love, and in the end, he realizes that happiness was never about escaping his past, but embracing it with the people who truly care for him.
