If you need to know, this is a 14 minute short story about a boy who has just moved into a new city, Chongqing, and feels out of place. He, by a turn of events, gets to know the "gangster type" dude in his same class. Though, they begin on a not so friendly note thanks to their prejudices, they slowly develop a bond that is hinted to be a strong one.
This was directed to promote members of TNT - Teens in Times, and they did a fairly convincing job. (To me at least.) It was cute, though I don't know what's up with the English title when the native one is a simple "Let's Wait for the Rain to Stop".
