Murasaki is the daughter of a landlord who possesses a quiet but extraordinary ability: by touching someone, she can see their future. Her monthly routine involves collecting rent from the tenants in her father's building, a task that always leads her to the door of Banri Shijima, a struggling author who is perpetually short on money. Month after month, Shijima offers the same excuse, promising to pay his overdue rent as soon as his work is published and he finally receives a paycheck.

Despite his unreliable excuses and disheveled lifestyle, Murasaki continues to support his writing career with patience rather than frustration. The reason for her tolerance is deeply personal; Murasaki has already glimpsed her own future through her power and knows that Shijima is the man she is fated to marry. This knowledge shapes the story, as the dramatic irony lies not in whether they will end up together, but in how their relationship will evolve from that of a landlord's daughter and a deadbeat tenant to something more. The narrative focuses on the quiet, awkward, and tender moments between them as Murasaki watches the man she is destined to love slowly work toward his dreams, all while the question of the month remains the same: Sensei, how will you pay this month?

The setting is largely contained within the apartment building, which acts as a small community hub. While the central relationship is between Murasaki and Shijima, the series introduces a rotating cast of other tenants that expands the world beyond their rent-collection routine. These include a fashion student, a nightclub hostess, and a former yakuza grandpa, each bringing their own quirks and small storylines to the slice-of-life narrative. As the story progresses, it moves beyond simple monthly rent collection to explore Shijima's gradual professional growth, Murasaki's determined personality as she navigates her preordained future, and the development of their unusual relationship. The manga is noted for its strong fashion sense in character designs and a distinctive art style that blends seinen demographics with shoujo and josei aesthetics. Throughout its run, the series maintained its focus on the delicate process of two people finding their way toward a future that one of them has already seen.
