When they were young, they made a private decision for life...
Now, they still remember...
Will they hurt each other because of misunderstanding?
Will that pure girl who has been beside him become cruel because of him?
Will the pure girl come back?
What would the boy who had been by her side and guarded her like an older brother do for her?
Will their misunderstanding be resolved?
With peach blossoms falling, will that be their ending?
