What to read after Drops of God: Mariage 1?

One last challenge stands between Shizuku Kanzaki and his father's fortune-to identify the wine his father called “The Drops of God” in his will. Problem is, he's up against Issei Tomine, a famous wine critic his father adopted shortly before his death. Alone and penniless following his journey around the world to gain knowledge and train his senses for the final showdown, Shizuku stumbles into a western-style izakaya to work for food and a place to stay. But when Shizuku uses his newfound smarts to save the struggling business, a competing chain launches an identical menu and enlists the help of a rising sommelier to go head-to-head with them. In order to stay on top and survive this brutal business, it all comes down to perfecting the food and wine pairings-the blissful mariage of flavors which delights the senses.
