The white-collar Amemiya Hotaru (Ayase Haruka) is actually an out-and-out homegirl! At a young age, she only likes to "leisurely" stay at home in her spare time, eating, drinking, sleeping, not going out, not socializing, and not falling in love. Compared with the dazzling image at work, the gap is more than ten million! One day, the boss of the company, Minister Takano (Fujiki Naoto), came to the house. It turned out that Takano was the real owner of the house. He recently moved back because of his divorce from his wife. At first, Takano was terrified by the "true face" of the otaku Xiaoying, and then he felt that he could "not regard her as a woman" and began to live under the same roof. Unexpectedly, the minister gradually found that he had a good impression of the confused and sloppy Xiaoying. Xiaoying, who was late to realize it, not only did not realize it, but also poured out her secret love to the minister... But when she really fell in love with the man of her dreams, Makoto Teshima (Kato Kazuki), she found that the other party did not seem to be the right person. A calm love triangle is about to begin!
