I know how you feel, but I also feel like this series is about the four of them. In the beginning, the focus was on Zheng Xi and Jian Yi.
however Mo and He Tian's relationship also required more development as well as the stuff with She Li. 

i think that while right now it's focused on them two, the series is still the four of them, and that now that this She Li arc is over, you might see a more balanced telling of the story.

just my opinion tho

Lets all go to that world together and find our peace
