Moko, who attends a school in Tokyo, has a fun life with her best friend Hikaru. My daily routine is to stop at a convenience store on the way home from school to eat sweets and chat. - One day, when she finds out that Hikaru is shoplifting and blames Hikaru out of a sense of justice, she says that she was able to do it "due to the stress of studying for the exam" and vows not to do it again. However, the next day, Hikaru, who shoplifted, was caught by the convenience store manager, but he put the product in this bag and blamed him for the crime.
