“This is the otome game I played!” She realized on the day before the story’s ending.
Is waiting for my conviction the only thing I can do? But, I did not do anything too cruel... Thinking so, the ending proceeds.
However, during the judgement, something that was not possible in the game happened. Tiarose was proposed to by the crown prince of the neighboring country.

Since I know how this tragic tale ends, I decided to do what I can to stop the ultimate destruction of the kingdom from the male leads. But the more I try to fix things, I can't help but notice that the storyline seems to veer farther away from what I read. Will this plan of mine work? Or will it just cause more harm than the original?
