The summer vacation has just begun, and the tension in the air is palpable as Yuzuru, Emika, and Shoiko prepare for a day of relaxation and unexpected intimacy. After a long first semester, the trio finds themselves back in Yuzuru’s calm and familiar room, ready to enjoy the break. While Shoiko and Miki plan a romantic trip with their boyfriends, Yuzuru and Emika are left to their own devices—until a curious exploration of Yuzuru’s room leads them to a hidden treasure: a book that promises a new kind of adventure.
As they flip through the pages, the atmosphere shifts from playful curiosity to a growing sense of anticipation. The book’s contents—images of seductive kisses and tantalizing encounters—ignite a spark of desire between them. Emika, who has never kissed before, is both nervous and excited, while Yuzuru, equally inexperienced, finds herself drawn into the moment. The two take turns exploring each other, from soft kisses to more intimate touches, each new experience deepening their connection.
The excitement doesn’t stop there. As the summer heat builds, so does their passion. They take turns tasting each other, sharing moments of warmth and intimacy that leave them breathless. The room becomes a place of discovery, where every touch and every glance carries the promise of something more. As the night progresses, the trio’s bond grows stronger, and the lines between friendship and romance begin to blur.
From playful teasing to deep, heartfelt moments, the summer vacation becomes more than just a break from school—it becomes a celebration of love, friendship, and the beautiful, awkward journey of first love. As they lie together, exhausted but happy, Yuzuru and Emika know that this summer will be one they’ll never forget.
