My Princess Is Sweet and Sassy

I was tired after watching 350, even after eating 5 chapters, it didn't end, with a look and a lot of psychology. The female protagonist also has no human rights. The male protagonist sent someone to keep an eye on her from the beginning. He would think that she had something to do and he couldn't say anything if he kept an eye on her. Later, I found out that the female protagonist wanted to ask for medicine or sent someone to follow him. It would not be good to protect him. He said that later on, the relationship became quite good. He sent a maid to the heroine to monitor him. He told him everything he did and said. He wanted to know and master everything about the heroine. He didn't say anything about the heroine's waistcoat. He looked at the heroine as if she were watching a play and secretly found it funny... This heroine is indeed quite ridiculous.
