Spoiler Alert
I'm not sure if I remembered it right so basically
Qu Cheng and Yue Yue never had a romantic relationship. It was one sided. Qu Cheng lied because he was actually insecure, I mean he's the only one chasing after Cinian and he was not quite sure if he's important in Cinian's heart. He thinks that Cinian will leave him if he knew about his past because they haven't been together that long. So he was planning to do everything he plans for their future as a secret and surprise him.

oh its on the later chapters around 115 or 116 which got deleted here because the uploader didn't have any permission to upload those chapters. the translator clearly stated not to upload to sites because someone is already uploading here. The chapters were exclusively for FB and now they just announced that they'll stop translating.
spoilersss....
Is Cheng's character going to be unfaithful now? or just a lying crap? after everything the mc has been through? No...
