What Kind of Substitute Is This?

Shen Qi admits that the stupidest thing he ever did was listen to his friends' bad advice and find a stand-in for his unattainable love. Five years later, Shen Qi can't remember his unattainable love or what a stand-in is. All he can remember is the beagle owner's book, I Once Wanted to Hug It and Jump Off a Building Together. Theme: Good things always show up when you least expect them.
