This is a super cute story. I usually dislike Chinese movies because there's something missing and they leave you with a bitter aftertaste ( they also have heartbreaking endings way too often).
But this was such a great surprise, the characters had such great depth and beautiful emotions. And it had many funny scenes as well.
I wished it was made into a drama so we could fully enjoy the events while they discover what's happening to them after the accident and how they try to understand how their connection works, it would have been hilarious, but for a movie I think they did a great job and it was very enjoyable.
Great ending as well! Absolutely loved it.
