Masamune-kun's Revenge

Makabe Masamune, once an overweight child who was teased as "Pig's Foot" by a girl, undergoes a transformation through years of training to become physically fit and attractive. His goal is to exact revenge by making her fall in love with him before breaking her heart.

Masamune receives a mysterious letter containing the phrase "Pig's Foot," prompting him to investigate its source and confront a hidden aspect of his past. His search leads him to an unexpected individual who possesses knowledge about his history.

Masamune, hoping to convince Aki to go on a date with him, joins forces with Kojuurou to challenge Aki and Yoshino to a test competition. The winner will earn a date with Aki, while the loser must endure the nickname Aki gave Masamune until graduation.

Masamune attempts to win Aki's affection by following tactics from the shojo manga *Barasute*, but Yoshino, who calls herself Master, advises him to change his approach. He shifts from aggressive methods to ignoring Aki in hopes of gaining her attention, with mixed results.

Masamune rescues Aki from a near car accident, only to be approached by the attractive girl in the car, who says she was waiting for him and embraces him. Shortly after, a new student named Fujinomiya Neko joins Masamune's class, causing Aki to grow increasingly distant and upset.

Neko makes an effort to gain Masamune's attention, but he remains unaware of her intentions. Upon returning home, Masamune discovers Yoshino and Neko preparing food for him, which unsettles him due to personal items from his past that he wishes to keep private.

After their exams end, Masamune and his friends travel to Tsunade Island for a summer vacation at Aki's villa, hoping to grow closer to her. With some encouragement—and a warning—from Yoshino, Masamune declares to Aki's family secretary, Yuigasaki, that he is her boyfriend, leading them to pretend to be a couple.

Masamune receives a call from Aki and notices a childhood photo of them missing from his room, suspecting Neko is responsible. He sneaks into Neko's room to investigate but is discovered, leading to an unexpected reaction from Neko.

Masamune rejects Neko, prompting her to disappear and leading the group to search for her. Aki expresses sympathy for Neko's rejection, and Masamune brings up the nickname "Pig’s Foot." They eventually find Neko, who begins recounting memories from the past.

A second Masamune, Gasou Kanetsugu, appears before Aki as summer break ends, complicating Masamune's pursuit. He discovers Kanetsugu is Aki's betrothed and notices Aki treats him differently, prompting Masamune to seek advice from Yoshino.

Masamune and Kanetsugu compete to create the best "Snow White" production for the cultural fair, with the prize being a dance with Aki. As their rivalry intensifies, an unexpected event disrupts both of them.

Following the conclusion of the cultural festival, the group celebrates at a karaoke after-party where friendly rivalries turn into a lively competition. Meanwhile, the question remains: will Masamune finally carry out his long-awaited revenge?

During a school trip to France, Masamune and Aki's class encounters Muriel, a young woman with dreams of becoming a manga artist.

Aki shares details of her past with Masamune, but he becomes unsettled when they recall a key life event in vastly different ways.

Gasou makes an effort to build a closer relationship with Aki, while Masamune has a serious conversation with Yoshino about an unresolved issue.

Yoshino reveals the truth about her past to Masamune and urges him to intervene before Gasou's growing relationship with Aki leads to complications.

Masamune unexpectedly interrupts a date between Aki and Kanetsugu, revealing himself as the Masamune Aki had met eight years earlier. To his surprise, Aki agrees to go out with him, and they begin a formal relationship, though Masamune struggles with mixed feelings.

Masamune and Aki spend Christmas Eve together, which also marks Aki's birthday, but their celebration is complicated by unexpected events.

Masamune attempts to uncover the reason behind the hives he develops whenever he is around Aki, following a ruined Christmas Eve date.

Masamune assists Yoshino following a minor injury, while Aki has a meeting with Gasou.

As Valentine's Day approaches, Yoshino volunteers to assist Aki in preparing a gift for Masamune. Following this, Aki goes on a date with Masamune.

Aki takes Masamune on a White Day outing, but the evening unfolds in an unforeseen and surprising manner.

Yoshino visits Masamune after noticing his frequent absences from school. Chinatsu informs her that Masamune has left school and is staying with their grandfather in Shinsu.

Masamune, Aki, and Yoshino face a critical turning point as their choices and relationships are tested under increasing pressure from external forces and internal conflicts.
