After they have a heated argument over their dying relationship, he wakes up in a parallel world where he is a literature teacher and Olivia is a world-famous pianist. Olivia is now in a relationship with someone else, and does not recognize Raphaël at all. Raphaël thinks the only way he can go back is to make Olivia love him again.
