The "Wakako Sake" series, based on the manga of the same name by Chie Niku, tells the story of OL Murasaki Wakako wandering around various bars and drinking alone. This work adds winter flavors such as monkfish and ark shell, as well as many delicious foods such as machi sushi and Mongolian cuisine that I have experienced for the first time. In addition, there is also a morning drink as "Wakako's morning life", and she sighs "puff", and the happy moment is recorded.
