S1·E540 The Charismatic Sisters, The Ugly Siblings

Episode recap

The episode opens with the arrival of three well‑known actresses who are described as charismatic. Their presence is the catalyst for the main competition, which pairs the guest stars with the regular Running Man cast. The ten participants are organized into three separate sibling teams, each team consisting of a “big sister” and one or more younger siblings. The format of the game centers on an allowance that the big sister must allocate to the younger members of her own family.

Throughout the segment the teams engage in a series of challenges designed to test their ability to earn and manage the allotted money. The allowance is not a fixed sum; rather, it is earned through the tasks that the groups complete together. Once the allowance has been distributed, the episode shifts focus to an individual assessment. The final penalty is determined by the amount of money each participant retains after the distribution phase. This rule creates an internal competition within each family, as younger siblings and their big sister must balance generosity with personal gain.

The structure of the episode therefore produces a layered contest: first, the three sibling groups vie against one another for the collective allowance, and second, each individual must consider how much of that allowance to keep for themselves in order to avoid the penalty. The tension builds as the participants weigh the benefits of sharing against the risk of being singled out for the concluding punishment.

The episode concludes without revealing the identity of the person who must carry out the penalty, leaving the outcome to be discovered by viewers. The format highlights both teamwork among family members and strategic decision‑making on an individual level, aligning with the variety‑show tradition of combining physical games with psychological challenges. The presence of the three charismatic actresses adds a guest‑star element that complements the regular Running Man cast throughout the competition.
