My Sister Is Not Yours to Touch - Episode 5

At a hotel meeting a woman insists that "my fiancé is Nathan" and is confronted by Winona, who says she is Nathan's sister. Accusations fly—Winona vows to stop the marriage—while someone finds the fire extinguisher empty and forbids calling for backup, fearing it will "blow this up before dinner with Nathan's sister." The clash escalates into intimidation: a drawing is seized, insulted, and a slap is threatened. The drawing turns out to be a student's, and someone asks, "You're a volunteer teacher?" The reveal undermines the woman's claim and leaves the outcome unresolved.
