What episode is Brother Wu's passion for Princess Zhu Huan?

Yongqi is not a sudden emotional episode, but she thinks the swallow is special at the beginning, then she doesn't control her feelings when she knows it's not her sister, and finally she confesses to the swallow. I don't know which episode you are asking. In the third episode, after the swallow was injured, the two met for the first time in Yuting and toasted each other, but Yongqi didn't know that she was a fake princess. In the fifth episode, the swallow pretends to be a eunuch and fights with Yongqi. Yongqi was very surprised and decided to help the swallow out of the palace. She also knew that she was not a real princess. Since then, I have been accommodating and indulging the swallow. In the first episode 1 1, Yongqi began to try to help them get a position. By this time, she should have liked the swallow, but no one else knew about it. In episode 15, Yongqi confessed her feelings for the swallow to Erkangertai. Episode 17 is the confession of a famous gazebo. .
