Saskia’s Determined Pursuit of Boris

Saskia (Delphine Wespiser), once again, will use her charm on Boris, inviting him for a drink, but he will resist her advances, preferring to return to his wife, Muriel (Lou Kuma Kudi), fearing he might lose her. That’s not all; Boris will tell Berthier (Khalid Maadour) and Bilal (Malik Elakehal El Miliani) that a Chinese distributor is interested in Phynoma, viewing it as a game-changing opportunity for the company.

Meanwhile, at Gustave Flaubert High School, Salomé (Elina Machet) finds out she has contact dermatitis. Claire (Mélanie Maudran) advises her to set aside all her beauty products for a week and use a more suitable treatment.

Will Sabine Call Off the Wedding?

Sabine (Gaëla Le Devehat) threatens to cancel her wedding with Hugo (Bibi Tanga) after discovering that her mother, Claudine (Catherine Wilkening), has not only taken over planning the reception but has already chosen the venue. Meanwhile, Céleste (Firmine Richard) returns from her trip to Egypt. Once again, Hugo’s mother is distant towards Sabine but close to his ex-girlfriend, Caroline (Agnès Ramy).

But things will not improve. Tensions rise between Céleste and Claudine, and Claudine makes a faux pas by revealing in front of Janet (Tonya Kinzinger) that the wedding reception will be at the same venue where she married Becker (Yvon Back).

Cécile’s Infidelity Discovered

Cécile (Marie-Gaëlle Cals), having been the victim of a car bomb attack, is between life and death in an induced coma. Her son, Achille (Matthieu Rodriguez), fears losing her. Meanwhile, Florent (Fabrice Deville) and Margot (Clara Botte) hold out hope for her recovery.

During the investigation into the attack, Élise (Malya Roman) discovers Cécile’s secret affair with Guillaume Sérignan (Joffrey Platel). Enraged by the infidelity, Florent confronts Guillaume! Will Cécile and Florent’s relationship survive this ordeal?

Ultimately, Sérignan is removed from the investigation when his alibi confirms he wasn’t present at the time of the bombing. So, who is behind it all? Meanwhile, Yann (Constantin Balsan) begins a relationship with Carole, unaware that she is hiding her true identity. In reality, she is Élise’s new girlfriend, Agnès (Anaïs Delva).
