Duan Fuyu took the initiative to transmigrate into a book to redeem the gloomy villain Song Jinnian, but seven years of dedication only resulted in a failed mission and watching her own death. Until the truth was uncovered, she realized that his coldness hid a belated deep love. To save him, who was desperate and rushed toward death, she discarded her memories and was reborn with him in another world. She became a beloved princess, and he turned into the humble craftsman Julian. To win back the woman who had fallen in love with him all over again, he built bridges to save the people, traveled far to enemy countries, and risked his life to complete six trials. But when the two of them were finally together, severe injuries and poison had already exhausted his life, leaving only an unfinished garden and a promise for the afterlife.
