A window separates the two worlds. With the courage to run to each other, the young people made a promise to elope. But reality lies ahead, and the enthusiastic expectations are ultimately defeated involuntarily. The moment of returning the token is the end of the heartbeat. The story tells the story of a two-way longing that ends in vain, and explores the difficulty of young people's passionate love against the shackles of reality. Some distances cannot be bridged even if they are desperately close, leaving only long-lasting regrets and unfulfilled promises.
Purpose: The story is written for all those who meet involuntarily: some loves are full of courage to rush to, but lack the luck to reach the end, leaving only long-lasting regrets that cannot be resolved.
