From my understanding, she was in relationship with Mars. Then, was forced to marry emperor, so she broke up with Mars. But Mars don't want to give up, so he followed her always and help her everytime. She still love Mars and I think the emperor is shitty towards her and Mars. And when she pregnant with Mars's baby, they probably scared that the emperor would find out. And they both probably worried what to do. And then Mars would decided to kill himself to somehow prove a point that the child is not his, so they can bury the secret.
So this is all bcz of the queen's cheating? I mean.....gaddamn
