Reitetsu Shachou to Kozukuri Kon: Hotel Ou wa Ai no Akashi ga Hoshikute Tamaranai

I want you to stay smiling by my side. Kasumi was proposed to on the very first day of meeting him. Her suitor was none other than Ichiya, a regular customer at the cafe where Kasumi works, affectionately known as the count with a sweet tooth. Kasumi had secretly been curious about Ichiya, who exuded an air of nobility like that of a count. However, for some reason, even though they weren't in a relationship, he suddenly asked her to help him build a family. At twenty-seven years old, with no romantic experience, Kasumi misunderstood this as a job offer under the guise of marriage. (Source: BisouBisou Comics)
