I was wondering what was up with that cover. I was like, who are these people? Am I supposed to remember them?
**SPOILER**
And if you're having a hard time remembering, this story is about a guy (Cheng Ke) who does sand art for a living. He meets and befriends a thug-like guy who likes to fight (Jiang Yudou). Jiang Yudou had a seriously messed up childhood (him and a bunch of other kids were raised to be cage fighting dogs called "Puppies") which left him with severe trauma. Cheng Ke helps him and finally convinces him to go to therapy after another Puppy comes to find them and tries to fight them. It's a bit of a dark story, but super cute.
Its messed up they changed the cover to something entirely unrelated. It makes things confusing when trying to remember what this is about.
