I don't really write reviews but I don't think this manhwa deserves such a low score. I would rate this story a 7.5.
The art is beautiful and the plot is quite good, especially starting from chapter ~50.
Also, the ML's backstory is very good.
My only issue is that the FL since she is quite soft, I prefer characters like Medea from Your Throne. I personally don't like the FL's weak and whiny personality but the story is good overall.
There are some pleasant surprises here and there, making this story a bit different from others in this genre (in a good way) even if it's not super duper unique.
Overall a good and quick read.
