[Parallel timelines + healing each other + secret crush + devoted to each other]
Zhou Ran spent more than half his life secretly in love with a girl named Lin Yue.
After graduating from high school, Lin Yue vanished without a trace.
When they reunited after years apart, he thought it was a new beginning, but it turned out to be the end.
The letter that was never sent,
The diamond ring waiting for its owner,
Both spoke of endless longing.
At fifteen, Lin Yue received a letter from herself three years in the future. From that moment on, the course of her fate quietly changed.
The universe is vast, but my thoughts of you broke through every boundary and every so-called truth, reaching you within an endless cycle.
