The manga has been serialized on Kodansha's online platform Comic Days since October 2022. It is a romantic comedy set in the early Showa period and follows the newlywed couple Lieutenant Takimasa and his wife Natsumi.

Plot

It is set in 1936, during the early Showa period. Natsumi Sekiya's father informs her that he has arranged her marriage to an Imperial Navy Lieutenant, Takimasa Ebata, without her knowledge, and that they are to be wed the following week. Although shocked and anxious about the sudden news, Natsumi follows through with the ceremony even though her fiancé cannot be present due to his work commitments. When Takimasa finally arrives two weeks after the wedding and they meet for the first time, he is distant and indifferent toward Natsumi, and their first few weeks of living together are filled with humorous misunderstandings. Despite these challenges, the two gradually grow closer.
