The whole story is basically from the male protagonist's perspective. Semi-open BE ending.
In 2005, Song Shu came to Wangye Village to work as a teacher, and met her mountains and seas here.
In 2005, Shanhai was repairing the faucet in the yard and looked up and saw Song Shu for the first time.
She was like a bird that landed in the village to rest. The bird sang to the big tree in the field, and the big tree provided shade for it, but then the bird flew to higher mountains and farther to the sea.
