Nothing makes sense. I waited 103 chapters for the misunderstandings to be cleared up but the pay off wasn't there. Her father didn't have a reason to pretend not to love her, and throughout the series he acted surprised when his daughter acted awkward around him and told him she knew he didn't love her. He gave her a dagger when he sent her into the dungeons, however that dagger wouldn't protect her from anyone, it made no sense giving it to her unless he wanted her to take her own life. Except when she did, he was surprised and acted like a tragic hero. Not only that, but his daughter spent like 5 minutes in the dungeon before the Crown Prince got there, which means that she REALLY didn't need the dagger at all. Her father also sealed her memories so that she wouldn't be traumatized, and then proceeded to traumatize her throughout her entire life by NEVER being there when she needed him. He even skipped her debutante ball.
The worst part is that this shitty father is loved by the people who read this manhwa. Why? He could've avoided making the FL suffer if he was more open with her, but instead he went out of his way to traumatize her. Then there's his way of raising the Crown Prince (ML). The late Empress entrusted her child to him, yet he didn't spare him even a bit of love or compassion. He was very harsh raising him, and then he was surprised that the ML grew up to be cold blooded and viewed as a psychopathic tyrant by the people. He always showed how much he loved his daughter in front of the ML and talked about her non-stop, yet he hid it from his daughter. Was he just trying to show off to a child starved for love? The ML was already busy trying to avoid assassination attempts made by the new Empress and his own father, just to have this asshole of a teacher treat him as dirt and show off his affection for his daughter at every opportunity.
It's insane how everyone loves and forgives this piece of trash. He could've ran away with his wife and daughter, yet for some reason he chose to stay and enter a contract with the Emperor, just to have the Emperor break the contract. And it never gets explained in detail why he entered the contract. It just gets glossed over as "he did it to protect his wife and daughter", when the contract doesn't protect them AT ALL. It just doesn't make sense. Fuck this guy.
