If you were to judge Mima Takayuki by his looks and competence at work, you would not guess that he makes silly mistakes a lot. His colleagues say that he's "unofficially in charge of soothing" everyone because of that.

Other than tutoring Shun, Hayate also tries to get used to his new job by getting to know the other employee, Souma. But intimidated by Souma's flashy style, he keeps messing up... But then Takayuki's calm voice lifts his up again...

Souma is worried about his older brother because when he's focused on work, he neglects food and sleep. After discussing it with his friends, Souma decides to make a bento lunch for his brother.

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...

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.

Souma invites Motoharu to go to the summer festival with Hayate, Shun, and Takayuki. After meeting Takayuki again, Motoharu also got to meet all the others. Having a natural talent for communicating, he's become friendly with all of them, except for Hayate. Hayate is always nervous, leaving Motoharu a little sad that they are not making progress. Therefore, Motoharu takes this opportunity to put a new idea to the test...
