Kikka Ichinomiya, a noblewoman who loves antiques, was raised by her aunt and uncle after her parents' death. However, when she reached marriageable age, she was almost sold to become the second wife of a wealthy man. Unable to bear it any longer, she ran away from home, and five years have passed since then. Kikka has adopted the name "Taro" and disguised herself as a man, working as a servant on an antique trading ship docked in England. It's a job where she can be involved with antiques, and she dreams of one day owning her own antique shop. In the midst of these not-so-easy but fulfilling days, Masamune Todo, the president of the trading company, visits the ship... "That's a very sloppy fake name, Ms. Kikka Ichinomiya." Kikka is surprised that Masamune somehow knows her real name, but then he proposes to her in an unexpected way: "Shall we get married?" https://www.cmoa.jp/title/1101422346/
