The story begins with a secret heartbeat in the mid-summer of senior high school. Strawberry Candy and Shell hide their secret love for three years, and their confession on the beach completes their youth. The protagonist has been together for half his life and settled down in a small town near the sea. When his daughter grows up and is admitted to his alma mater, he replicates his father's youth experiences. The gentle love is passed down from generation to generation in the evening breeze, breaking the fate of regretful parting in youth.
Concept: The passionate love of young people cannot withstand reality after all. Growth is about constant loss.
