**A Ballooning Adventure: Natsuki's Surprise in the Closet of Helium**

Natsuki's Childhood Imagination In the tranquil setting of the after-hours Literature Club, Natsuki found herself gravitating toward a peculiar curiosity. Having recently discovered an expanded epilogue from an alternative version of "Doki Doki Literature Club," her interest piqued during one of her manga-reading sessions. Intrigued by the possibilities it presented, she decided to explore more. One day, after the club meeting had come to a close and everyone else had left, Natsuki lingered behind. She often hid snacks or manga in the club's closet, but today she was searching for something different. Hidden among the decorations from various events was a small closet filled with supplies—including colorful helium tanks typically used to fill balloons for festivities. Natsuki had always been petite, almost to the point of frustration. As she moved some boxes aside, a mischievous idea sparked in her mind. What if, for just a bit of fun, she used one of the tanks on herself? With a mischievous grin, she inspected the tanks until she found one that was full. She paused, briefly considering the absurdity of her idea, but her curiosity got the better of her. She cautiously secured the nozzle of the helium tank and, with a deep breath to steady her nerves, placed it, somewhat awkwardly, in a place she never imagined she would. Turning the valve slowly, she immediately felt a strange but not entirely unpleasant sensation. Her stomach began to expand, filling with the lighter-than-air gas. The sensation was unlike anything she had experienced; it was as though her body was growing lighter with each passing second. Moments later, her petite frame expanded noticeably, her stomach now round and balloon-like. She giggled nervously, poking her now distended belly. It felt surreal. With a curious look, she noticed that she was gradually lifting off the floor. Natsuki let out a delighted squeal as she began to float around the room, her initial nerves giving way to childlike wonder. She drifted between the desks and around the bookshelves, experiencing a sense of freedom and weightlessness that was wholly new to her. After a few minutes, the reality of her situation began to set in. As fun as this was, Natsuki knew it couldn't last forever. Gently, she navigated herself back towards the helium tank, managing to turn off the valve with some effort. She found herself slowly descending, her inflation gradually diminishing until she was back to her normal size. Natsuki couldn't help but laugh softly at her adventure. As she glanced around the empty room, she was certain she would keep this amusing little escapade to herself. It was a whimsical experiment that had brought her a few moments of unexpected joy. Returning the tank to its place, Natsuki tidied up the closet and gathered her belongings. As she left the Literature Club room that evening, she felt a sense of lightness in her heart, a playful secret that added a touch of magic to her everyday life. And so, Natsuki's unexpected journey into the whimsical world of helium inflation became a fond memory—a story she would chuckle about in the quiet moments, a special secret holding a promise of wonder and curiosity.
