Shiki Souma is a cheerful student at a vocational school who's not bothered by his own blunders; sometimes they even crack himself up. When a friend talks about her future, he realizes that he has a lot of things he wants to achieve, but not enough strengths yet.

Despite it being a precious day off, Takayuki has agreed to watch his older sister's daughter Ririka. When Ririka badgers him into going to the park to have their bento lunch, Shun spots them and desperately tries to remember what he meant to say to Takayuki.

Takayuki has been picked to lead the project to promote a movie adaptation of a novel. In order to prepare for the meeting, he devours all the other works of the author, who curiously has the same name as a childhood friend of his, Igarashi Motoharu. On the day of the meeting, Takayuki's completely in awe because Motoharu keeps correctly guessing facts from his childhood...

Popular author Motoharu is not at all bothered when he makes a blunder. When he's at a meeting to discuss the promotion for the upcoming movie adaptation of one of his novels, he meets Takayuki, his friend from grade school. Later, this brings back old, pleasant memories... To Motoharu, who always had the dream of becoming an author, Takayuki is an unforgettable friend who unwittingly gave him a push he needed back then.

Souma goes out with Hayate and Shun to see the movie adapation of Igarashi Motoharu's book, the movie that Takayuki did the promo campaign for. Seeing Hayate being even more excited about the movie after seeing Takayuki's ad makes Souma want to create something that will move people in similar ways. After the movie, the group runs into Motoharu and end up going to the mawarimichi cafe together. On the way there, Souma asks Motoharu a certain question.

Hayate is helping Shun with his summer homework and suggests he reads Igarashi Motoharu's novel for his book review assignment. However, Shun doesn't like reading anything but manga, so he thinks he should just ask the author and contacts Motoharu. Meanwhile, on his way to Mawarimichi Cafe, Souma sees a bunch of people dressed for the summer festival and thinks they should all go.
