On an ordinary night in 2030, Shirou Fukushima never expected his life to change. After a late shift at work, he finds a mysterious woman unconscious beneath a lamppost-someone who seems oddly familiar, yet entirely unknown. Driven by concern, he brings her to safety, only to discover she has no memory of why she was there... or how she got there. As they begin to coexist under one roof, a quiet connection blossoms. But strange coincidences, buried memories, and growing questions threaten the calm. Why does destiny seem to pull them closer with every passing day? Sometimes, a single encounter is all it takes to unravel a hidden truth.
