This is a story about Li Xiao and Li En.
The beginning is "I want to take you back to my grandma's house and watch the sunset together until we both fall asleep." Jay Chou's "Simple Love"
Later it was "You have never heard of it, vows are like a Ferris wheel of happiness." Eason Chan "The King of K-Song"

I am Li Xiao, looking for a lost soul among the vast number of people...
