Nagasumi’s mom and Sun go shopping for groceries, leaving Lunar alone with Nagasumi. Lunar plans to make her “slave” help her study for school since she is getting zeros on all her tests. Eventually it gets to the point where Lunar starts to come on to Nagasumi while outwardly stating that she would never fall in love with a human. Through many badly timed, but well-meaning errors, Nagasumi ends up being engaged to Lunar.
