An otaku high school student, Tomoya Aki, designs his very own dating-simulation game. In order to make his desire a reality, Tomoya must persuade a few eccentric "creators" from his school.

A chance encounter with a beautiful girl during spring break inspires Tomoya to make a dating simulation video game. He tries recruiting Eriri and Utaha to assist him.

Tomoya asks Megumi out and gives her a lecture on how a perfect heroine should be like. He invites her to his home for an even more detailed lesson!

Tomoya continues to procrastinate despite a fast approaching deadline for his project proposal. Eriri and Utaha wonder if he's really serious about creating a dating sim.

Tomoya sets up a meeting with his recruits to discuss the game. After seeing Megumi with a boy, he can't help but feel jealous!

Utaha manages to write out the plot of their game, but it might not be what Tomoya is looking for. Megumi and Tomoya go on a date.

Tomoya leaves Kato in the middle of their date to meet up with Utaha. She takes him to a hotel, and they spend the night together. Alone…

While Tomoya is preparing for the Summer Comiket, two familiar faces from his past show up. Will this affect his game and all the preparations?

Megumi makes a concerted effort to understand dating sims. Later, Megumi and Tomoya assist Izumi during Summer Comiket.

After Tomoya hurts Eriri's feelings by praising Izumi's book, Utaha and Megumi urge him to make up with her in order to keep their group together.

After an argument with her dad, Michiru runs away and decides to crash at Tomoya's place for a while. In the circle meeting, it is decided that background music is needed for the game. Will they find someone to help them out?

Tomoya continues his attempts to recruit Michiru to his cause. Her critical words, however, cause Tomoya to question the dedication of his circle's members.

The group goes to see Icy Tail's first-ever concert. Before performing, Michiru's bandmates reveal a startling secret.

The team has come to the pool of a luxury hotel to do research for a swimsuit event for their game. As always, Utaha and Eriri are fighting, Michiru is doing her own thing, and of course Megumi is being aloof. Episode zero is here to bring you the swimsuit episode fans have been waiting for!

One and a half years ago at Toyogasaki Academy. Utaha confirms that the library is carrying the light novel she wrote Metronome in Love. She leaves and gets stopped along the way by Eriri Spencer Sawamura. We finally get to see how Eriri and Utaha meet. What exactly happened between them?!

Utaha and Tomoya go out on a date in Ikebukuro to celebrate the completion of the script. After going around to a book store and movie theater, they have dinner at a restaurant. That's when Utaha asks Tomoya whether she should attend a nearby university or one located in Kansai for college. Tomoya gives her his answer at the end of the date. Hearing it, Utaha decides to take a certain action.

Tomoya and the others arrive to meet Izumi, but to their surprise, Iori is there waiting as well. Iori reveals that his Dōjin Team, Rouge en Rouge, is making a new game that is in the same genre as the game Blessing Software is working on, and that Izumi will be in charge of its art. Tomoya believes in his team members, but Iori tells him that he is confident his game's story will be better.

Tomoya has noticed a fatal flaw in the script Utaha had written. While her script reads amazingly as a novel, it does not hold up very well as a game script. As the director, Tomoya decides the script needs to be rewritten and begins revising it. Fortunately, Utaha comes in to help as well after composing herself, and the two of them work together to improve the writing as a game script.

With the script rewrites and additional character route, game production has been significantly delayed, and it's becoming apparent that Eriri is running behind with the art. Utaha points out the quality doesn't reflect the time she's putting in. Even so, Tomoya trusts that Eriri will deliver in the end. So Eriri withdraws herself to her secluded family villa in Nasu Kogen to focus on her work...

Eriri finally finishes the artwork, but she collapses with a fever as she tells Tomoya she's done.

The game Tomoya and his colleagues completed "cherry blessing" gained a lot of popularity on the Internet because of Eriri's art and Utaha's script, leading them to sell out all their copies at their booth, and receive a massive amount of additional orders.

Replaying "cherry blessing", Tomoya notices details that makes him realize how dedicated Megumi had been to the game's development.

Tomoya celebrates Utaha's graduation from Toyogasaki Academy, and tells her that he would like to continue making games with the current members of the team.

After the meeting with Akane, Eriri had every intention of not working for Akane. However, Utaha points out that she agreed with her comment about her slump and that she should think about the opportunity this presents. Some time later, Eriri calls Utaha over and convinces her that she is out of her slump and is able to draw better than ever, while also letting her know that she has accepted the offer to work on Field Chronicles XIII. With Eriri joining, Utaha decides to join the project in more of a supervisor role resulting in both girls leaving the circle. While Tomoya discusses the future of his next project with Iori, Iori lets him know that he and Izumi have left Rouge en Rouge feeling that they could not do what they want by remaining in that circle. Tomoya goes up that slope where he met Megumi a year ago, and Megumi is waiting for him.

Tomoya is heartbroken by Utaha and Eriri's departure from the Dōjin Team, but Megumi takes the opportunity to ask Tomoya out on a date again. Back at Rokutenba Mall, the two of them go around the different stores reliving their previous date here. They visit a hat store last, and Tomoya buys her a certain hat to thank her for cheering him up and to repay her for the glasses she gifted him earlier.
