If a girl teases you, that means she likes you! Unfortunately, Akiteru knows from experience that isn’t the case. Because every girl he interacts with shows him nothing but scorn, and he’s not scored a single date from it! Luckily, he’s more concerned with securing a spot for him and his game-development buddies at his uncle’s business. But when his uncle throws him a condition that involves playing the part of his daughter’s boyfriend, Akiteru has no choice but to take it. What will his best friend’s sister Iroha, who bullies him relentlessly, think of the news?

As old charades end and new ones begin, the intricate system of secrets and lies holding the Alliance together threatens to collapse like a house of cards--not that Akiteru's noticed. He's been a bit preoccupied with Iroha, who he can't help seeing in a new light. It would figure, then, that his uncle would pick now to show up. So long as he's around, Akiteru's going to have to work double-time to sell the angle that he and Mashiro are a real fake couple. Dealt this bum hand by fate, can Aki come up with the perfect bluff, or will he fold? Can any gambit survive intact while Iroha's a player? And when the summer festival finally comes, just who will Akiteru wind up watching the fireworks with?

The Alliance is caught in a maelstrom of trouble as secrets are covered and uncovered everywhere you look! Unaware of this spiral of secrecy, Akiteru’s started seeing Iroha in a new light... And just his luck, his uncle shows up to make sure Akiteru sticks to playing the role of Mashiro’s fake boyfriend! Akiteru’s got no choice but to set up a (fake) date for the summer festival. Will someone like Iroha really sit back and just watch? What’ll become of the Alliance in this perfect storm of trouble? And...just who will Akiteru wind up watching the fireworks with?

The first time Akiteru met his friend’s little sister, Iroha, she was soft-spoken, with a diligent air about her. So when he heard she was interested in joining a gang—one led by none other than Otoi—he began to suspect there was more to Iroha than met the eye. When he intervened, things only got more complicated. And in the end, Akiteru formed bonds with unlikely friends for years to come. It’s finally time to unravel the secrets of the Alliance’s past! How did Akiteru come to form the 05th Floor Alliance, and why did Iroha decide to make him the victim of her teasing?

With the culture festival behind them, it’s finally time for some rest and relaxation! Or it would be, were it not for the two-mom tag team ambush being sprung on Akiteru. With both mothers keen on interrogating Akiteru about his relationship with their daughters, there’ll be no time for relaxing at all! While Aki deals with them and tries to figure out what happened between his aunt and uncle, a battle rages on behind the screens as Mashiro and Iroha compete for his affections. Will things come to a head on the upcoming field trip, or does more disaster await?

With the summer festival behind them, it’s time for Akiteru to get back to finding Iroha a friend! But nothing ever goes according to plan. What’s he to do when his friend’s little sister doesn’t seem to have it in for him anymore? How can he find her a friend she can be annoying with when she doesn’t want to be annoying anymore? When Akiteru tries to talk some sense into her, she instead talks him into competing at the school’s culture festival for the title of...Queen Nevermore?! It’s now up to Akiteru to defy the odds and become the prettiest girl at school! But will that really help Iroha get back to her usual (annoyingly cute) self...?

The biggest event of your high school career has to be the class trip! Akiteru and his classmates are off to Kyoto to deepen their understanding of Japanese culture. But with Iroha out of the way, Mashiro’s more concerned about deepening her (fake) relationship with Akiteru! Too bad her plans are thrown into disarray when it turns out there’s a third girl vying for his affection. While Mashiro tries to come to terms with this new development, Iroha goes on a long-distance offensive to annoy Akiteru—but will that be enough to satisfy her? With trouble like this brewing, the class’s “relaxing” trip to the hot springs will be anything but!
