Deep in the mountains, along a rugged, treacherous path, lies the legendary lake—suddenly appearing in a clearing, its waters an impossibly deep, mesmerizing blue. I stood breathless, certain this was the fabled lake of the northeast, where long ago a beautiful girl drank the water, wishing for eternal life. The water was said to be delicious beyond measure, yet drinking it would create an unquenchable thirst. She gained immortality, but transformed into a great serpent, becoming the lake's eternal guardian. I came here seeking the magical water, hoping it would grant me enhanced stamina and instant recovery from fatigue. As I nervously scooped the water to my lips, a girl suddenly appeared before me—long wet hair, white dress, large round eyes. She stared at me, then smirked, rushing forward to cling tightly to my body. Her touch was icy, paralyzing me with shock. She pulled me closer, slowly stepping backward into the lake, wrapping around me like a giant snake. Panic and fear surged, but I couldn't move. Water rose past my shoulders, and eventually, I closed my eyes, surrendering completely to her. When I came to, I was standing in Shibuya's Center Street. Had it all been a daydream? Yet her face remained vivid in my mind. And for a moment, I could've sworn she smirked at me again. In that instant, I knew—I would seek her out once more.
