Jules, 38, has been having an extramarital relationship with one of his partner's friends for more than two years. The couple regularly visits her at birthday parties or dinners, sometimes at their home, more rarely at hers.

“I try not to think too much about morality…” Jules seeks to protect himself, he who recognizes that he is “putting himself in great danger” in his emotional and family life. On paper, the 38-year-old Parisian ticks all the boxes of the ideal son-in-law.
