Secret Keeper
Hopelessly Devoted
Makabe Masamune is a second-year student of Class 2-B at Yasaka Private High School, carrying a meticulous plan for revenge beneath his now-refined exterior. Once a heavyset boy cruelly nicknamed "Pigleg" in his childhood — a taunt he believed came from Adagaki Aki — he spent eight relentless years reshaping both his body and identity, even going so far as to change his family name, all to orchestrate the perfect revenge: make Aki fall for him without revealing who he truly is, then coldly reject her. He harbors an intense fear of spiders, a small crack in his otherwise steeled composure. The only person privy to his secret is Yoshino Koiwai, whom he deeply respects and addresses as "Master." Yet somewhere along the way, the plan began to unravel — not from failure, but from genuine feeling, as his heart quietly surrendered to Aki herself.
His resolve is tested time and again: he pushes through a severe fever during the school festival to assist Class A, sharing an unexpected kiss with Aki that earns them the title of "Best Couple" by the entire student body. During a school trip to France, a heated confrontation with Aki over mismatched childhood memories drives a painful wedge between them. Only upon returning to Japan — piecing together clues from Muriel Besson's manga drafts and a chance realization at home — does Masamune uncover the truth: it was never Aki who called him "Pigleg," but Yoshino, who had been concealed in the mansion suffering from chickenpox. Confronting Yoshino, then rushing to Aki's side, he delivers a decisive blow to Kanetsugu and resolves to shield Aki from further pain — honoring both his own feelings and Yoshino's quiet, earnest wish.
