I'm Not a Cheater, but I've Admitted to You the First Yat.

Cristei: "I was not good at keeping a secret. Noone really is" He says he's going to trust you until he doesn't, and if he finds out about the cheating then he'll leave. Li asks him why he thinks no one has ever heard of this kind of thing before. The pair have been together for two years; they are now engaged.
