@Taotilychee Thanks for posting the tumblr link here. MDL wouldn't let me do it earlier... :(
I think this is indeed the best ending. It was so heartwarming and tied up the story of both couples nicely (so many awesome moments in there <3). Also, I consider it canon since the scriptwriter of the drama posted it :D
Also in weibo, when the scriptwriter posted this ending, they apologized for the rushed ending and said that it was caused by time issues leading to logical problems that have upset a lot of people. They were sorry and they themselves can't accept what they wrote originally. The scriptwriter told fans to stop watching at 10 mins before the end of episode 37 and read their posted script afterwards. That is the proper ending according to them. :)
I think since the team can't film this anymore, they put together an edit which is as close as they can get to this ending by the scriptwriter.
