At first I was a bit cautious because of the complaints in the comments about how the MC cries a lot, and the story seems to go nowhere.
But that was not the case.
There's a plot related reason for why her tears are a key discovery, so of course the plot would move in a direction to make her cry --and yet it was not contrieved, and the MC when aware of it tries her best not to. Part of it and what is does is resolved, which for a webtoon, it was done quickly enough. Moreover the plot is intriguing and both the MC and ML develop as characters.
True, perhaps many expect the MC to become shrewd and savvy, but that's not exactly in par with her personality. She seems to be developing in some other ways, namely, courageaous, confident and trusting. Development which, in my opinion, suits her charming airhead personality just fine.
Also the plot keeps moving and is never stagnant. There's a lot of comedy, but when it needs to get serious it gets serious --and even some of the comedy moments turn out to be foreshadowing.
It's a good read.
