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.

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.

Hayate is about to go into the Small Animals Cafe when Takayuki approaches him because he didn't want to go into a cafe full of girls and couples by himself. Once inside together, Hayate gets really excited about all the animals, while Takayuki feels the soothing effect of them by just watching.

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...

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.

Hayate is badgered into going to a mixer by his friend who was just dumped, and thinking that he needs something to jolt some excitement into his everyday life, he reluctantly agrees. Once there though, he can't quite get into the vibe and is about to leave when one of the girls approaches him.

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...

It's raining. Hayate forgot his newly purchased plastic umbrella at the bookstore. Luckily, Souma runs into him and they both go back to the bookstore to look for it. Once there, Hayate bumps into Takayuki and they realize that they both like the same author. But being too excited about the conversation, Hayate forgets his original mission and leaves without the umbrella. When he rushes back in from the outside, a certain person hands him his umbrella, but for some reason, he's also carrying a shoe horn...

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.

Takayuki has to do the PR for a new horror game, so he ends up trying the demo with Souta and other colleagues. However, Takayuki doesn't really like gaming nor horror, so he is not too enthused. Deciding that he has to do this for work, he jumps in anyway, but then the graphics are too high fidelity and real, that he gets scared. Not wanting to be alone at home, he asks Hayate if he can stay the night. For some reason, Shun was already there, and then...

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.
