The Emperor's Royal Preceptor Princess Exploded

It doesn't matter that Liu Yihan woke up after a hangover and came to an unknown country inexplicably. The important thing is: I am actually the master of Ling Haotian, the man above ten thousand people, the emperor of this country! And he is also the emperor's royal physician! What shocked Liu Yihan even more was: she actually had a fiancée! This fiancée is still a princess! What happened to this world? Here, the princess comes to me every three days and tries to please her in various ways. Over there, the emperor always takes up his own time in the name of his apprentice. Okay, the master is the master, she wants to maximize the rights of the master, and she also wants to carry out this gender to the end. However, when Liu Yihan discovered that the entire country actually belonged to her, she was so happy that she actually owned the entire country! However, when Liu Yihan sat on Ling Haotian's bed with tears in her eyes, she regretted why she always provoked him in the first place. Regret? Is it useful? It's too late!
