Miwa Kurushima and her partner Yukari Higuchi scour the city for a bartender capable of managing the counter at the renowned Hotel Cardinal. The hotel"s chairman insists on one criterion: the chosen mixologist must master the legendary elixir called the "Glass of God." Miwa"s lack of clarity about this requirement causes her hunt to stall, as every candidate she interviews fails to satisfy the chairman"s exacting standard.
Hidden amid the lively lanes of Ginza, Eden Hall offers a tranquil refuge. The bar is run by Ryuu Sasakura, a young virtuoso whose intuition always delivers the drink that soothes his patrons" anxieties. Each pour is served with modesty, giving comfort to anyone who walks in seeking relief. Its walls echo with laughter and whispered confidences, making it a favorite for those who need a quiet moment away from the city"s clamor.
When the chairman first encounters Ryuu, he is stunned by his deft skill and vows to bring him aboard Hotel Cardinal. He soon becomes a regular patron, attempting day after day to persuade Ryuu to leave Eden Hall. Yet even with Miwa"s help, securing this exceptional bartender proves harder than anticipated.
