This seriously will be easily one of my favorite webtoons. It's different from the other ones with the death flags. Here, I really feel that if she makes the wrong choices she's going to die and there's also depth in the main character: how she feel towards the villainess, how they look like eachother in some points,...
Also my guess is :
she will choose for option 3, because 1 and 2 are too villain (and not rational I think).
If she chooses for 3, it will maybe look like she's being dominated by the maid, but I think there will be dialogue that would make it a save option.
