The story follows a male protagonist who buried his belief in soulmates and fate twenty years ago after a major loss, choosing to live a guarded life built on routine and emotional distance. That carefully managed control shatters when a 20-year-old female student walks into his lecture hall. She looks at him with an inexplicable familiarity, as if she has been waiting her whole life to find him. Despite his instincts to keep his distance to protect his career and her future, an intense, unexplainable connection and a series of strange coincidences pull them together.
