Sakuraba Kotaro inherited a small grocery store after his father passed away. He relied on the support of his mother-in-law, Nagisha, and sister, Nagisa, to keep it running smoothly.

The person responsible for this proposal was none other than his estranged brother who had abandoned their family's business.
