Lin Xiaoman never imagined what kind of waves that summer would cause in her life.
When the salty sea breeze carried fine sand and hit her face, she met Gu Yan, a boy as gentle and dangerous as the sea breeze. His appearance was like a carefully woven dream, making her gradually sink into sweetness. However, when the truth recedes like the tide, what is left is a devastated beach.
At the same time, the long-distance relationship between best friend Su Yuqing and her military boyfriend Zhou Hao is also going through the test of time. Letters carry longing, but they cannot resist the cruelty of reality. When misunderstandings and suspicions emerge like hidden reefs, their friendship also faces unprecedented challenges.
Witnessed by the sea breeze and waves, the fates of the four young people were intertwined. They experienced the sweetness and bitterness of love, the test and rebirth of friendship, and stumbled on the road to growth. When the tide recedes, they will finally understand: some love, like the sea breeze, is gentle but hard to catch; some people, like rocks, have been washed away but always persist.
This is a story about growth, love and friendship. It tells the story of how a group of people born after 2000 learned to love, learn to let go, and finally find their own direction in the wave of youth. When the sea breeze blows again, can they still find their original heartbeat?
