During a family meal, her younger sister, Diane, who seems perfect in every way, announces her future marriage: this is the straw that breaks the camel's back for Joséphine, who has not got a man in her life.

Just before the plane's departure, Joséphine suffers a panic attack and is taken to the hospital, unbeknownst to her friends and family, whilst her luggage is misplaced.

Joséphine chooses to continue the deception and decides to hide in her own apartment, which was temporarily loaned by Chloe to their colleague, Gilles.

Joséphine, through false tears, then claims she came back after Marcelo's death, but Gilles and her friends don't believe the story and leave angrily.

Joséphine, trying to make a fresh start, decides to interrupt her sister's wedding after discovering that her fiance, Aymeric, cheated.
