Hai Wang ascended the throne with the court's full support. He did not take Sheng Lingxin as his Empress. In fact, he did not marry anybody in his first two years which probably became the only major dissatisfaction of the retainers toward him.
Most likely due to the dreams she had when she was in a coma, Sheng Lingxin seemed to have a sudden change of heart. However, in this lifetime, it seemed she was destined to always chase but never catch up. The difference was that this time, it was her fault that the person who used to like her so much was now no longer looking at her the way he did before.
Fate managed to straighten her out into realizing she was destined for Hai Wang, but sadly it was already too late. Not even fate would be able to make a prideful male lead accept someone who made him feel like he a joke for so long.
