Sugar Dog Life

A love story interwoven between Sakuraba Isumi, a short, baby-faced university student who is a great cook, and Amasawa Kyosuke, a tall, sincere police officer with a natural, easygoing charm.
Twenty-year-old Isumi is mistaken for a minor and nearly gets taken into custody by Amasawa. Later, Isumi runs into Amasawa again at the convenience store where he works part-time. From then on, every time they meet, Amasawa asks for recommendations for late-night snacks. Concerned about Amasawa's eating habits, Isumi offers, "How about I come over and cook for you?" Visiting Amasawa's home, they grow closer through home-cooked meals.
