I love to watch those movie with time travel plots. This movie story evolves a 38 years old guy named Wang regrets over something he had done in the past. Back then, he met his secondary school mates and he try to undone what he did. I really enjoyed watching their times together. Who dont have regret in their life. The story also link with the talented deceasd singer, Tom Chang and very good selection of songs. The cast selection are great. Not so much about die hard love story but more on admiring someone you love and you want her to do well. I like the ending very much.
