In his past life, Gu Chen was the Defender-General of Great Gan, spending his entire life in armor and protecting the mountains and rivers. He granted his wife, Liu Ruolan, a First-Rank title of honor and a lifetime of glory. Yet on her deathbed, she said to him: Gu Chen, I have actually always loved your good friend. You never understood me. Only then did he realize that everything he poured his life into was, in her eyes, just that of a dull man who understood nothing of romance. Five years later, he died defending the border, and the emperor suspended court for three days for him while the whole of Great Gan mourned. His soul drifted into the Imperial Ancestral Temple and heard Princess Changning, Zhao Hongling, express her yearning of many years for him, as well as how she remained unmarried for his entire life. Reborn into a new life, the story of Gu Chen and Zhao Hongling begins from here.
