Once shunned by the art world, Perception Art has taken the world by storm. The medium has evolved to incorporate all five senses, allowing viewers to completely immerse themselves in pieces of art. As the son of the creators of this movement, Kazuya Yamanashi has inherited his late parents' talent and creativity for Perception Art. Now enrolled at Eisen High School, the first-year has his sights set on becoming the best Perception Artist. Kazuya has a reason besides ambition to attend this prestigious institution, as he hopes to make amends with his estranged childhood friend, third-year student Kyou Takise. But the rift between them may be difficult to repair since Kyou and Kazuya belong to different streams of study at the school. As luck would have it, the two are partnered for the exclusive Staircaser competition, in which the winners will represent Eisen for the year. In order to stand a chance against their competitors, Kazuya and Kyou will have to learn to set aside their differences first.

Amatsuyu Jouro Kisaragi is a completely average second-year high school student who has two dates over one weekend⁠—with the student council president Sakura Cosmos Akino on Saturday, then with his childhood friend Aoi Himawari Hinata on Sunday. Sadly for Jouro, both girls proclaim their love for his best friend Taiyou Sun-chan Ooga, the ace of the baseball team. Accepting each of their requests for advice and guidance, he is now responsible for helping the two girls win the heart of the same guy. Unbeknownst to his friends, Jouro's friendly and obtuse image is all but a ruse designed to cast himself as the clueless protagonist of a textbook romantic comedy. A schemer under his cheery facade, he makes the best of this unexpected turn of events with a new plan: get Sun-chan to fall for either Cosmos or Himawari and take the other as his own prize. But Jouro's last-ditch effort is threatened by the gloomy, four-eyed Sumireko Pansy Sanshokuin, who surprises Jouro with not only her knowledge of his secret personality but also a confession to the true self he hid for all this time. Stuck in this hilariously messy situation, each of the five students must navigate countless lies, traps, and misunderstandings to come out on top.

Mahiru Shiina is worthy of her nickname Angel: she is a divine beauty loved by all, and she excels in both academics and athletics. Shiina lives in an entirely different world from Amane Fujimiya, her next-door neighbor. Despite living so close together, they have never spoken once. But their silence is broken when Fujimiya spots Shiina gloomily sitting on a swing amidst a heavy rainstorm and lends her his umbrella. When Fujimiya catches a cold the next day, Shiina wishes to return the favor for the umbrella by nursing him back to health. Believing that this would be their first and last interaction, he silently appreciates her kindness. However, Shiina—who cannot help but worry about Fujimiya's lack of tidiness and proper nutrition—begins to cook and clean for him. As the unlikely pair spend time together in Fujimiya's apartment, they explore the true nature of their relationship and the gentle emotions that emerge from it.
