be warned: this movie tells lots of love stories without any coherence.
The only intention of this movie seems to be showing love in many different ways.
Each story has only a few minutes, so there is no development of characters and nearly no plot. Just an sketchy idea of a plot. The writer tried to build in turning points that aimed to surprise the viewer. However, that just didn't work out because you didn't get to know the characters in before or these "jokes" were just silly.
This is a movie about love that fails to reach your heart. A dozen times. Or even more, I don't know and I don't care.
