Futami Shun is a high schooler with good looks who excels at all types of sports. He is a tryhard who hates losing, and he wants to pass off his flubs as intentional.

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.

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...

"Hayate and Takayuki have come to the stadium to cheer Shun on in his handball tournament, but for some reason Shun's friend Souma is missing. It turns out that he went onto the wrong train... Meanwhil Shun is really fired up about winning as much as possible to prolong being together in a team with his teammates who will retire after this event, but the hype backfires and he can't quite perform right..."

Shun gets a letter from a younger girl at school. After opening it, he realizes that it's a love letter and is about to immediately reject her when his friends stop him. Instead, they convince him to write a letter back. But since he has never really written a letter, let alone a response to a love letter, he agonizes over what to write. So he asks Hayate, Takayuki, and Souma for advice, but none of them are particularly helpful...

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...

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...
