In the twelfth episode of season 37 of Les  Mystères de l’amour  , broadcast on Sunday, November 9, 2025 on TMC, Nicolas ( Patrick Puydebat ) continues to cheat on Hélène with Ingrid. Even though she has returned from vacation and he is being very attentive to his wife, he can’t resist secretly kissing Ingrid.

Ingrid ( Carole Dechantre ) continues to reassure Nicolas, stating that he isn’t cheating on Hélène. She’s content with just a kiss. Later, Étienne ( David Proux ) arrives at his friends’ house. He wants to speak with Ingrid privately. Mégane’s partner admits that he misses her.

Étienne in love with Ingrid in The Mysteries of Love

As a reminder, Ingrid used Étienne to make Nicolas jealous. The strategy worked, but Étienne seems to have fallen in love with Ingrid. He asks her why she isn’t replying to his messages. She admits she’s not interested right now and rejects his advances. He ends up joining Nicolas and Jimmy ( Tom Schacht ) to blow up balloons for Fanny’s ( Elsa Esnoult ) and Christian’s ( Sébastien Roch ) party.

Then, Étienne wants to talk to Nicolas alone about Ingrid. He asks him if he knows anything about her distancing herself from him. Nicolas claims he knows nothing and asks if he hasn’t fallen in love. Étienne assures him that he’s still in love with Mégane ( Claire Thomas ) and reminds him that he even wants to have a child.
