--The story begins with a message in a bottle.
--She is certain the person who sent it is the one she has been waiting for all her life.
--Not only because his name is Liu Xiao, which seems to pair with her own, He Huan, as if fate had brought them together in a past life!
--But also because his message in a bottle says, "Until the mountains lose their peaks, the rivers run dry, winter thunder rumbles, summer snow falls, and heaven and earth unite, only then will I part from you." What could be closer to the love she has dreamed of?
--And so, the two of them begin an online romance...
--When they finally meet in person, they are delighted to discover that each looks just as they had imagined!
--But to be together, they must both face the obstacles and hardships of reality.
--They overcome every difficulty and get together. Then an accidental miscarriage leaves her unable to conceive again.
--But this is only the beginning of their misfortune...
--Though life is difficult, they both hold fast to the vows they made at the start.
--She loves him and doesn't want to hold him back. He loves her and cannot bear to leave her.
--Until one day, they arrive at the snowy mountains on this plateau. Beside a mani stone mound, he sings that timeless verse again: "Until the mountains lose their peaks, the rivers run dry, winter thunder rumbles, summer snow falls, and heaven and earth unite, only then will I part from you."
