Seventeen years of silent watching, the wind in the alleyway hides the young man's thoughts. During their childhood sweetheart years, her secret love was like thin smoke, until one day it was ignited by him himself.
Purpose: Taking the growth of childhood sweethearts as a thread, it shows how secret love quietly takes root in getting along day and night, interprets pure emotions that do not require passionate confession and can withstand the test of time, and conveys that "the deepest love is often hidden in the most familiar companionship."
