In the halls of a Japanese high school, two young ladies, Kotora and her best friend, find themselves alone and curious. They've seen each other change, bathe, but never like this. Their eyes meet, filled with a newfound longing. Kotora's heart races as she imagines her friend's soft lips on hers, their bodies entwined. She tentatively reaches out, tracing her friend's arm, feeling the goosebumps. Her friend leans in, their breaths mingling, but a sudden noise breaks the spell. They pull away, hearts pounding, leaving the moment hanging in the air like an unspoken promise.
