Before morning homeroom. Haruto, having returned from Australia, opens the classroom door to find Akane, who had been eagerly waiting for him. Looking somewhat awkward, Haruto pulls Chloe—the tall international student standing beside him—closer and speaks as if he's braced himself.
Haruto's first friend! Nice to meet you, Akane!
Akane's face contorts in despair, and she is left speechless. Indifferent to the heavy atmosphere, Aine tightly tugs on Guest's sleeve.
