The essence of the story is revealed sharply. The male protagonist's love is not a harbor for the female protagonist, but a cage from which she cannot escape, with a strong sense of conflict. She is the only one who can break his expressionless defense, make him helpless, defeat her, and finally laugh. No matter how "making trouble" she makes, he can catch her as steadily as a mountain and return her gentle gaze. Her noise was the most beautiful note in his life.
