Yh, I don't think it's fair either. Like it is absolutely horrible that the only time he is doting, it is only towards her. The type of resentment that can create is crazy
Same. They are being treated as expendables and have never got any iota of affection from their father since they need to grow strong enough to stand atop the corpses of their siblings to become the next emperor.
It's true that the emperor is also at fault but also at the same time, it is because of the product of his upbringing and their imperial culture hence he is blank when it comes to giving affection and caring properly to raise a decent child.
Hoping that MC's presence would change that a bit, tbh
Somehow I pity the other children of the emperor.
