I Also See Jun Xi and I Also See the Clouds

In that border pass called Huayun Pass, a boy named Yun Wuxin left and returned again and again. There was a girl he missed and she also missed him. Yun Wuyi couldn't stay in Huayun Pass because of the demons in his childhood, but Hua Bujing wanted to protect the people in Huayung Pass and didn't want to leave. Therefore, the two people who missed each other strangely became farther and farther apart. Yun Wuyi took another trip to the world to see how others missed someone, and seemed to understand how to miss someone. When the inner demons finally dissipated unexpectedly, Yun Wuxin returned to Huayunguan on that New Year's Eve, but the girl he wanted to protect disappeared with Huayunguan. How should he miss her?
