Hirotta Inui-kun to Koi wo Suru

Overview

Usami Totoko, a high school sophomore from this spring, has been living alone for a week since her parents were transferred overseas. She was enjoying a carefree life, but one day a rude convenience store clerk told her bluntly that "eating convenience store food every meal is dangerous." This comment prompted Totoko to try cooking for herself, but she accidentally set off the fire alarm. When she went outside to ask for help, she was reunited with the convenience store clerk.
