Lu Yingtang, the second young lady of the Yongning Marquis Mansion, is good at embroidering begonias, but she is just a tool for her husband to decorate his appearance. On the spring night of the 23rd year of Taiping, she walked towards Qi Wang Xie Yuan who was waiting under the crabapple tree at the back door - the man who saw through the "silent madness" in her embroidery at a glance. From Chang'an to Jiangnan, from prison to freedom...
Everyone in the Yongning Marquis Mansion said that the second young lady, Lu Yingtang, died of a sudden illness and was only eighteen years old.
Only the weeping crabapple at the back door knew how determined she was as she walked toward the man in black clothes under the tree that spring night.
