She is like sunshine and he is like the deep sea.
She is close to everyone, but he is alienated from everyone; when she encounters danger, she dares to rush forward, and he will always guard her retreat.
Xia Qingyu never sheds tears in front of others. Because her tears will condense into crystals and preserve the strongest few seconds of memory when she shed tears.
At the auction, a deep-sea crystal worth tens of millions and named "Poseidon's Tears" caused a sensation.
Only Xia Qingyu knew that those were the last tears left by her mother who was buried at the bottom of the sea many years ago.
In order to find out the truth, she boarded the national deep-sea scientific research vessel "Zhulang", where she reunited with Jiang Xingye, a young man she had rescued seven years ago. Today, he is the youngest deep-sea crystal engineer and still wears the drop of crystal she dropped on his wrist.
Intention: No matter how deep the sea is, it cannot bury truth and love.
