After hearing Samiyi's request, Tan Rou felt that it was preposterous. She was the princess of this country; if she wanted to leave, it had to be by her own efforts. No one else could help her.
Moreover, Tan Rou was not an international spy. She wasn't here for tourism, and if she left, she might never come back, perhaps even assisting Princess Samiyi once.
But if she decided to work with the King, then, in order to maintain the machinery, her company would definitely have to send someone over every year. When the time came to meet with the King, she didn't know if she should maintain the mechanical equipment or handle the princess's affairs.
