She is the shadow he picked up, a substitute for the passing white moonlight, a puppet in a gorgeous cage at the mercy of others. Lu Zhiyan gave her a life without worries, but he also used the cruelest way to crush her sincerity and dignity bit by bit. Congenital heart disease dragged down her body, and a belated awakening could not save her lost life. When he finally saw his love clearly, she had already burned to ashes in endless pain. This is a sadomasochistic relationship without redemption, the ultimate BE of not being able to love but regretting it too late, a bone-gnawing tragedy of substitutes and paranoia, illness and misunderstandings. The rest of his life is long, and only endless regret is left to accompany him until his old age.
