The fifth year of the Republic of China, Suzhou.
Song Yuanzhi made a decision: to marry into the Gu family, in exchange for her sweetheart, Shen Yanqing, to live in Nanyang.
Gu Zhongxuan, the second young master of the Gu family, was as gentle as jade and treated her very well. It was so good that she felt heartbroken, so good that she felt guilty, and so good that she wished she could fall in love with him.
But the person in her heart never moved away.
She didn't cry the night Shen Yanqing left. The night when Gu Zhongxuan became seriously ill, she cried all night - not because of love, but because of fear. She was afraid that she wouldn't be able to keep the only person in the world who was kind to her.
What she owed Gu Zhongxuan could never be repaid in her lifetime.
She owed her heart something that she would never be able to repay in her lifetime.
This is a story about debt and repayment, being loved and being unable to love.
Zhang Ailing-style desolation, the elegance of a deep house in the Republic of China, and the depth of a courtyard that a woman can never leave in her life.
