I got stuck in a time loop trying to save her. On the 101st cycle, I discovered that the only way to survive was to end my life before meeting her. When I stood on the edge of the rooftop, she, who was not supposed to know me, grabbed me from behind and said, "You are not allowed to die secretly alone."
Concept: The story uses a time cycle as a framework to explore the philosophical paradox of love and sacrifice. When salvation becomes futile and sacrifice becomes the only solution, love becomes an inquiry into "existence" itself in the confrontation between fate and free will - death is not the end, but being forgotten is.
