There are so many stupid isekai stories where the MC doesn't use her brain - ffs, this isn't one of them. It's a tad frustrating watching the MC not realize the hero's feelings for her, but it's quite understandable given the situation she's in (she may know the novel's plot, but she's not omniscient--something most isekai stories don't get right, therefore undercutting ALL narrative tension). The MC is quite clever at playing politics and using the knowledge of the world to try to change the situation to her advantage, and is a good mix between being good-hearted and politically astute (her personality isn't just wow, look at how pure I am~!). The writer also doesn't let misunderstandings linger to the point where you beat your head on the wall.
This is quite good, please don't let the angry comments deter you from reading it.
