Xue Yang made him into a fierce corpse...but he has regained his consciousness so he is able to live on. He has A-Qing's soul in a spirit-trapping bag as well as your own. He wanted to travel the world and nurse both spirits back to health. I think even if he can't, he's just glad that in a way you are walking together again.

[He thinks their story is one of the saddest he has ever had to learn about. He just wishes that Xingchen could perhaps have a little bit of peace in the hotel. A chance to heal a little.]

I know you feel guilty about a lot of things, Shishu..but I hope you will let yourself heal in this place.
