XUAN SHI STEALING A MARCH ON THE OTHER SUITORS.
Honestly though, this is why I don't understand when people say these two don't have chemistry. It's not giddy infatuation, but a deep understanding of one another that gives the possible of a mature relationship. Xuan Shi believes in Ling Qi so hard that it drove him to be a better person and grow up. He has his own ambitions, but he's also not afraid to pursue the feelings he has. And Ling Qu has learned from him and grown, specifically with regards to the power of narratives and stories. I don't think the same can be said of her relationships with her other suitors. BQ seems more likely to learn form her while LQ does her own thing, and the flirtation with Meng Dan is cute but I want to see more of their interactions once he as skin in the game.
Plus, I love the idea of Ling Qi being the lynchpin of a Cai-Bai-Xuan alliance.
The fact that he just wanted to know if there was a chance and was totally willing to drop is courtship if there wasn't speaks to his growth from when we first met him.
