Overview
This is the first manga about menus by Sayaka Yamazaki, the creator of "Shimashima," "Siren," and "Andaz: Rina's Story." It features recipes you'll want to try and the daily life of a slightly goofy cohabiting couple. Two people and one cat have a mysterious encounter. As a result, Shu-kun and Aya-chan start living together, and their pet cat, Mike, cooks dinner for them!? (Source: Bungeishunju, translated)
