Episode 5 recap: Li Caiwei investigates the killer of Shen Huai Jin.

Liu Jingshu, unable to argue with Li Caiwei, returned to the side of the princess with a dejected look. The princess scolded her for not being able to handle such a small matter. The princess had been trying to make Liu Jingshu seduce Shen Huai Jin, hoping to make him make mistakes and anger the emperor, thus stripping him of his position as the crown prince. However, she also worried that Liu Jingshu would truly fall in love with Shen Huai Jin. Therefore, the princess no longer forced her to approach Shen Huai Jin and ordered her to bring back Shen Huai Jin.

As Guo An applied the medicine, he commented to the prince that Li's attitude towards the prince had changed a lot, and it was clear that she was jealous of Liu Jingshu. Shen Huai Jin said that he allowed her to indulge herself and even took beatings for her, so it was normal for her to treat him well. Guo An warned the prince that his actions might anger the prince. Shen Huai Jin said that he intentionally wanted to provoke the prince. The reason he indulged in extravagance was to divert the wealth of the prince's mansion because Yunjin Tower, Wanhua Building, and Desheng Gambling House were all his properties.

If Li Caiwei truly cared for him, he would reveal all these truths to her when the time came. Li Caiwei grabbed Lanxin and asked her if her engagement to the crown prince was approved by the emperor. Lanxin confirmed it because of the marquis's outstanding merits, and the emperor pitied her for being lonely and without support, so he arranged this marriage. However, Lanxin told her that in this mansion, only the crown prince genuinely cared for Miss.

After the events of today, Li Caiwei also felt that Shen Huai Jin was a righteous person and decided to help him find the person who harmed him. She first sorted out the people related to Shen Huai Jin and prepared to investigate and identify them one by one. Shen Huai Jin noticed that Li Caiwei was secretly following and attacking him but found it amusing and did not let on.
