What's the entanglement between Qingchuan and Prince in Palace Lock Heart Jade? please reply me back as soon as possible.

No, Qingchuan was given to the prince by Xinlian. When she woke up, she found that she was sleeping with the prince, but nothing happened. Her clothes were changed by the old demon. 1988, she thought Qingchuan had lost her innocence, and later she was fine. She cried with Qingchuan in her arms because her 90-year-old brother wanted to test her innocence. Of course, she didn't agree. She was crying when she was saved.
