A bottle of water: Dark obsession
Yui Kurokawa is a 19-year-old girl living alone in Tokyo. Her daily life is simple—college, a part-time job at a convenience store, and returning to her small apartment at night. Everything about her life is ordinary, with nothing truly remarkable.
But everything begins to change after a meeting in a narrow alley one night.
There, Yui finds a mysterious man who appears injured, sitting alone under a flickering streetlight. Driven by a mix of anxiety and sympathy, she gives him a bottle of water before leaving without asking too many questions.
From that night on, Yui’s life is no longer normal.
The man begins appearing in various places—on the streets, in trains, even near her workplace. At first, Yui assumes it is just a coincidence. But day by day, his presence becomes increasingly impossible to explain… as if he is always in the right place at the right time.
At the same time, strange incidents start following her footsteps.
Yui must uncover who this man really is—and why, ever since that brief encounter in the alley, her life has never been the same again.
