- The MC. He was 29 years old and few years has passed since then. His persona is kind of childish in many occasions. And I have read only about women putting so much attention, concern and effort in their faces like him and then behaving like a baby and expecting to be seen as manly... And he is so full of himself that behaves as annoying sometimes. Like in the next paragraph, in a situation where he is in front of the emperor and officials at the courtroom:

Xu Huaiqian was a little annoyed with Emperor Changsheng, who always interrupted him. Could he please wait for him to finish speaking?

I wonder if he thought he was the main professor in a lecture giving a speech. His transmigrated persona is not even an excuse because he has adapted pretty well to mostly everything. But he is no different than a brat when he is supposed to be the top scholar. To behave like that in front of the highest authority and the whole gabinet. And he is being collected this time while venting his anger because he is se*ually frustrated. I have read only about spoiled female leads behaving in a similar way and only those holding very high positions like the empress or the most favored concubines.

- Another point is the MC "sickly beauty" persona.

- The ML is so the OTP that is beyond comprehension.

- The whole pair dynamic gives the impression of a mix of reverse role and gender. Maybe the author wanted to make something more original but it does fall under the typical OTP.
