The emperor has a genuinely super interesting backstory which is way sadder than the ML. He was sexually abused multiple times. All he has is his brother and even that is taken away from him. I sincerely hope the author will find a middle ground between portraying him as a victim (oh and ,by the way, the relationship he had with the empress is called grooming hope it will be portrayed as such)and the stupid/shitty way he organized his brother marriage.
I don't know if they are blood related but no matter what. Why ??? Why do you keep making strange shit like this. Still crossing fingers that the little bro isn't in love with his sister...
To me, it gave off vibes like the little bro actually wanted to make Ian jealous to spur him into action, because he probably knows his older sister is in love with Ian and it's mutual :)
