Episode 20 recap: Shen Huai Bin condemned his own family for the sake of justice.

When Liu Jing Shu left, she entrusted the evidence of the crimes she committed, which led to loss of life, to Shen Huai Jin by secretly giving him the stamped money. Shen Huai Jin and Li Cai Wei bid her farewell, and Liu Jing Shu left in a carriage. Shen Huai Jin told Li Cai Wei that everything Liu Jing Shu had said before was true.

Li Cai Wei mischievously replied that, of course, it was true, as she had personally experienced all of it. Shen Huai Jin decided to give the evidence of the crimes committed by the royal concubine to Shen Huai Bin, after all, she was his birth mother, and he wanted to see how he would handle the situation. Shen Huai Bin looked through the account books and was astonished to discover the outrageous actions of the royal concubine.

Shen Huai Jin let him make his own decision. Shen Huai Bin understood the principle of righteousness and stated that the royal concubine had become insane due to her conflicts with her brother's mother, and it was necessary to stop her as soon as possible. Shen Huai Bin handed over the account books to the prince, who became furious and deemed the Liu family to be immoral. He punished Liu Jing Shu to reflect on her actions at the ancestral tomb. Shen Huai Bin felt troubled and drank alone. Shen Huai Jin and Li Cai Wei approached him, and Shen Huai Bin mentioned that in ten days, it would be the eve of their wedding ceremony, and according to the customs of Qi Kingdom, they would drink flower tea. He promised to offer them the finest flower tea on that day.

Li Cai Wei believed that Shen Huai Bin was responsible for Shen Huai Jin's death on the eve of their wedding, so she and Lan Xin ambushed outside Shen Huai Bin's room for several days and finally witnessed a masked person coming out of the room.
