Here is a quaint, old-fashioned café where the scent of freshly brewed tea always lingers. The owner, Midori Hanatsubaki, is a somewhat eccentric lady with a fondness for black tea. Together with her newly hired part-time employee, Daisuke Kise, they open the café for another lively day.

そこは、いつでも淹れたての紅茶が香る昔ながらの喫茶店。
店主の花椿みどりさんは、少し不思議な紅茶好きのお姉さん。
最近入ったアルバイトの黄瀬大助くんと一緒に、今日も元気に開店です――。
