A guy by the name of Shino is in love with a girl named Maruyama, and he asks his friend Akira to help set him up with her. Unfortunately, Akira ends up dating Maruyama instead of hooking her up with Shino. Depressed, Shino heads down to a black tea shop run by a guy named Shuuji to drown his sorrow by pigging out on cakes. Sometime in the past, Shuuji had a spat with a friend or something (referred to only as “that guy”) who thinks the best way to make up is send mysterious unmarked packages of randomly selected tea. I guess he has a history of sending dangerous gifts, as Shuuji gives Shino the tea “on the house” to see if it’s poisoned. Well, the tea appears to have been laced with a genie, who promptly grants Shino his desire to be with Maruyama... But be careful of what you wish for.
