The plot is good without isekai. There's no much unnecessary boast of our MC's abilities but her daily interactions prove her worthiness. The characters around her are consistent to their persona and their development throughout showcase the reality.Not all characters here are brainless other than that person. Even the rumors and the royal family is not it seems to be. The emperor might be a muddle-headed but his trait of being a leader can be seen. All of here are maintaining some facade and it's normal in political scene which is the thing that made me read more.Beside that, the trope which is the ML saves the MC but remain anonymous but secretly observing and stalking. The intriguing part of romantic development is... meh.
