The lively Tingluo Island has taken in two seventeen-year-old boys
Su Tingyan, who grew up in the local area, met Pei Sufan, a rebellious young man who came across the sea.
They promised to stay on the island together, but due to an accident overnight, Little Sun became taciturn and returned to Linwu Island with Pei Sufan's ashes regardless of everyone...
"Didn't we agree to return to Linwu Island together after retirement? Pei Sufan, you are the one who likes to lie to people the most." "This island where we have agreed to live together has the same sound of tide every year, but I can no longer wait for you to land."
Purpose: Falling in love is not worth parting between life and death, only memories remain to keep the promise
