After being unable to endure her boss's power harassment, Saintess Alm leaves her workplace. She packs her belongings, buys an abandoned park with her saved salary, and decides to live there, surrounded by a barrier. Determined to spend her life alone within the barrier, Alm faces visits from her former colleagues and a prince, trying to persuade her to return. However, she has no intention of going back. Her former boss, who secretly had high expectations for her, tries to get her out of the barrier but fails repeatedly, earning the disdain of others as 'the man who oppressed the saintess.' This is a mental battle between a harsh, tsundere boss and a saintess with the lowest self-esteem but the strongest abilities, set in a desolate park.
