I was really hoping that Irene would learn her lesson and turn herself around, it even seemed to be positioning it as that being the case, with her stress eating because her sister was no longer with her. They even built up sympathy for her with the prince's abuse of her... Only for her to be so cartoonishly evil and selfish.
It's disappointing, because I feel like it would have been much more interesting to see the sisters mend their relationship then whatever this is.
Also, it kind of makes the MC's life up until this point seem pointless -- what did the MC struggle so much for in raising her sister, if the sister turned out like this?
Also, why would someone so self assured and self absorbed be so lead around by the prince? Surely the Sister wouldn't have agreed to hurt herself for his sake. This just screams being under some sort of hypnosis, but more likely, it's just poor character consistency.
