As introverted colleagues at a travel agency in Tokyo, Takuya Oohara and Rika Honjouji both cherish their happily single lives. After work, home is where they feel most at ease: Takuya unwinds with his cat, while Rika studies various maps. However, an uncertain future looms over their treasured tranquility when their company plans to open a branch office in Alaska within one year and transfer an unmarried employee there. During a day off, Takuya and Rika accidentally meet and, despite never having spoken before, open up to each other about their relocation fears. Feeling encouraged by Takuya facing the same predicament, Rika suddenly proposes a daring solution—to pretend to be engaged for 365 days. Takuya accepts, but little do the two know that the path to marriage may, in many ways, change forever the very lifestyles they struggle to preserve.

The Taishou era didn't end in 15 years, but went on for another 25. In order to protect her waning family, a girl resolves to marry a man she doesn't even know the name of. However, just before the marriage was to take place, the girl's younger brother mysteriously committed suicide by self-immolation and was found holding an old book in his hands. Appearing before the bewildered young girl was the "Imperial Library Intelligence Asset Management Bureau," more commonly referred to as "Fukurou." According to these men, there exists "Maremono," which are books that greatly affect their readers. On top of that, ever since the incident involving the girl's younger brother, she unwittingly gains the ability to see "Auras" (the sentiments of the Maremono which manifest as bright lights and are usually invisible to humans). It was as though fate were trying to drag the young girl in its flames. And then, even though apprehensive, the girl chooses to venture outside her bird cage. Jealousy, hatred, scorn, compassion, and love. What awaited the girl was the darkness of betrayal that had already begun to bewitchingly inlay the imperial capital. Toyed by and swayed within that darkness, will the young girl finally reach the truth after her struggles, or...? (Source: MAL News)

Thus begins Sunako's hectic life with abrasive Kyohei Takano, ladies' man Ranmaru Morii, calm Takenaga Oda, and friendly Yukinojo Toyama.
