Jonas, a 40 something Parisian, is still desperately in love with his ex-girlfriend Léa. When he knocks on her door to confess his feelings and she turns him down, he ends up at the café downstairs.
　　Inspiration strikes and he sits down to write her a long love letter, dodging everything he was supposed to do that day. What begins as a last attempt to get her back surprisingly turns into a vivid musing on the state of his life.
　　Over the course of a day, helped by a wisecracking bartender and an array of patrons from the neighborhood, Jonas has to face his past relationships, his uncertain future and, most of all, himself.

影评:

1,还是要有一点爱的，如果想要长长久久的走下去，无论发生什么都不离不弃的话。

2,曾以为，你就是我幸福的起点，曾以为，有了爱就会不离不弃，曾经满怀幻想能够与你携手共赴遥远的天际，朝起同行，落幕而栖，而如今一地的落红飘零，让我如何去拾起，岁月的转角处一个挥手，就是永久的别离，你给我的只是一个起点，而我却走向了孤独的旅程，看不到完美的结局，更觅不到漂泊的归期。

3,这辈子，能够相守固然是好，无法相守，只是因为不适合。有些你爱过的人的确只是个过程，他在你生命里出现，是为了使你茁壮，使你终于知道这一生你想要的是什么，你始终追寻的又是什么。

4,如果一个姑娘想嫁富翁，那就不是爱情，财产是最无足轻重的东西，只有经得起别离的痛苦才是真正的爱情。

5,在错的时间遇上对的人是一场心伤;在对的时间遇上错的人是一声叹息;在对的时间遇上对的人是一生幸福，所以我想，我是幸福的!因为能遇见你并且和你心心相印。
