actually i don't understand why people don't find this worth watching maybe they can't connect to the story or didn't felt the way the actors show this story, but for me its very much relatable when you go through out something and it has an impact almost control all of your mind and nerves then you can't help but hallucinate this story explains the feeling of terrific incident and the how much can impact of that incident affect any person's life if it gets worse then you can't focus can't feel emotional attachments
and the ending i find it abrupt but there is a possibility that Qing Fei is emotionally unstable and had hallucination of XZZ that she finally mets him in last because at the very different angle you can see hints that she can't accept that XZZ had already left and wanted to wait for his return as Xing Zhe Zhu said to Qing Fei, she can't always lie to herself and has to accept that XZZ already left so there is a possibility that Qing Fei had an illusion at last that Xing Zhe Zhe already returned to her and that's why the title called A BEAUTIFUL LIE anyways for me its emotional and really good :)
