In the episode of the primetime series aired on March 28, Nicole (Maja Salvador) and Adrian (Jericho Rosales) end up having sex during a work-related trip to a resort.
Meanwhile, an unsuspecting Monica apologizes to Adrian, with whom she has a son, for being caught up with the demands of her father (Christopher de Leon) and their family business.
The reconciliation has Adrian deciding against confessing what happened between him and Nicole, as he had planned upon returning home from his trip.
As the episode showed a sex scene, "The Legal Wife" on Friday had a Strong Parental Guidance rating, which also served to caution viewers about the sensitive subjects tackled.
"The Legal Wife," which is under the direction of Rory Quintos and Dado Lumibao, airs weeknights after "Ikaw Lamang" during ABS-CBN's primetime block.
