When suspicion starts to become reality, Tulaya (Yogurt Natthachach) — confident in her husband's love and loyalty — begins noticing Chris's (Gap Thanawet) odd behavior. This leads her to gather evidence to seek a divorce. Unbeknownst to her, Chris's mother is assisting in covering up all his wrongdoings to protect her son, the family's hope. This leaves Tulaya blinded to the truth, forced to cry alone over her shattered trust and inner pain.
However, what seemed like an external issue soon invades the Phrova household. Tuangboon (Euro Waratchathip), Chris and Tulaya's son, unknowingly fuels the fire by introducing his father's mistress, Nalin, to the family as his gaming friend. This sparks a cutting confrontation at the dinner table between the wife, the mistress, and the gathered family members.
After Chris admits to an illicit relationship with Nalin, Marisa (Nok Sinjai) barely stays seated. She summons Nalin (Ben Rewinyanun) to discipline her with a slap. But this time is different: Nalin reveals her darker side by threatening Marisa with a secret video clip between herself and Chris, then raises her hand to strike back. Although Nalin only threatens, this is enough to shock Marisa into collapsing to the floor.
For the first time, we see Marisa's vulnerable side — a mother who does everything to achieve her goals and bear the consequences of her beloved son's actions. How will Marisa handle this? Can she maintain control? Will Tulaya find a way to resolve the problems and keep the family together, or will it end in divorce?
