La vie compliquée de Léa Olivier

Léa moves to Montreal, leaving behind her best friend Marilou and her boyfriend, Thomas; when she starts her new school, she makes a blunder and gets noticed for the wrong reasons.

Léa befriends the queen of the simpletons while Thomas tries to make amends for his betrayal; seeking to integrate Léa into her gang, Maude decides to help her change her look.

Worried to see Sarah hovering around Thomas, Léa goes to Sainte-Marie to mark her territory; she's disappointed to see that Thomas doesn't come to pick her up, busy doing a "job" with Seb and JP.

To heal from her heartbreak, Léa decides to accept Éloi's invitation and attends a costume party; her presence doesn't sit well with the simpletons, especially Marianne, who tries to get closer to Éloi, but Alex only has eyes for her.

Léa decides to take her mind off things with Alex while Thomas settles his score with Sarah's boyfriend, but Léa is unable to let go; she accepts Katherine's help to put her past behind her by removing Thomas from her life.

Léa spends quality time with Alex while Marilou tries to clarify the status of her relationship with JP; Léa wants to keep her relationship a secret for fear of being seen as Alex's new trophy, but she still receives the wrath of her enemies.

Léa accompanies Alex to Éloi's birthday party and finds herself jealous of his conquest; while Léa is more confused than ever, Marilou and JP are living the perfect love story.

While trying to share her feelings with Éloi, Léa finds herself in a romantic misunderstanding. By confiding in Annie-Claude that she has feelings for someone without knowing if they're mutual, she piques her interest.

Léa receives a visit from Marilou in Montreal, who delivers the news she's been dreading for so long; in Montreal to see Ariana Grande's show, Marilou visits Léa's college and meets Maude.

Léa has no news of Marilou and finds herself the target of a rumor started by Maude; accused of plagiarism, Léa tries to defend her honor; her troubles aren't over when things turn ugly between Katherine and Félix.

Léa uses an unusual tactic to reveal to Maude that her ex is playing games behind her back with one of her friends. While the plagiarism rumor still circulates, Léa decides to confront the director to regain the right to write for the newspaper.

Léa surprises Marilou in Sainte-Marie for her birthday. Knowing that Léa will be at the party, reconciled with Marilou, Thomas decides not to go; he thus spoils the surprise Sarah had planned for him, who is not over the disappointments.
