In Victor Hugo’s famous poem, demain des l’aube, many have formulated their own adaptation of the plot. Subtitled in English, while the poem is read in French, this story involves the consequences of commitment in a relationship. The notion that love lasts forever couldn’t be further from the truth in this heartbreaking short.
Hugo’s poem has its own page on the French Wikipedia.
