Episode 15 recap: Cang Han Yu refused Nan Si.

Nan Si called the doctor to come and see Cang Han Yu. He asked the doctor how Cang Han Yu was doing, and the doctor said that Cang Han Yu was fine. Nan Si asked the doctor to leave the medicine behind. Nan Si asked Cang Han Yu what was wrong, and Cang Han Yu said that he was in good health. Nan Si suggested that since he was healthy, she could give it a try herself and approached him, scaring Cang Han Yu.

Nan Si said that as Cang Han Yu's husband, he must learn these things, and Cang Han Yu must study. Cang Han Yu said he didn't want to learn, but Nan Si insisted that he had to. Nan Si forced Cang Han Yu to learn, and Cang Han Yu had no choice but to comply, feeling that it didn't matter to him what the outcome of his learning would be.

Cang Han Yu wanted to say that he couldn't learn, but there was a nanny here teaching him. The doctor came over and told the national teacher that Nan Si and Cang Han Yu were doing well. The doctor said that Cang Han Yu wasn't really sick, he was just pretending.

The national teacher was also very happy, thinking that it was worth it to choose him as the man. In just a few days, he had captured the princess's heart. Nan Si also looked at Cang Han Yu and unexpectedly, a little girl came over and said that her parents were well chosen. Nan Si asked who the little girl was, but she didn't say.

Cang Han Yu pricked his hand, and Nan Si was also very anxious.
