The animation is adapted from the work of the same name by Japanese light novelist Iruma Rengen. Niwa Shin (voiced by Irino Miyu) is a simple young man from the countryside. This time, he is about to enter high school and comes to a bustling metropolis. The endless stream of people and the dazzling streets make Niwa Shin excited, and a plan to increase his youth points comes to mind. The plan is that if you talk to a cute girl or make a fashionable move, your youth points will rise, and vice versa, so that it will no longer be a dream to become a crazy and cool young man before graduation. In the metropolis, Niwa Shin lives in his aunt's house. Unexpectedly, in the home of his aunt who always thought he lived alone, there lived a radio girl named Elliot (voiced by Asuka Okame) who looked very strange in all aspects. In this way, Niwa Shin and Elliot's cohabitation life kicked off. With such a girl who makes his youth points plummet by his side, can Niwa Shin's dream still come true?
