In the third round, the participants' water intake is severely restricted, enforcing strict rules designed to provoke intense urges to urinate. Four girls take on this grueling challenge, with the one who holds it the longest earning the highest score. 1st place receives 3 points, 2nd place 2 points, 3rd place 1 point, and 4th place gets 0 points. To ensure fairness, all four girls first urinate together at the start. Afterwards, each draws one card, and whoever picks the joker receives the "special treat card." This card contains a malicious instruction that must be carried out while enduring the urge to pee—designed to inflict strong psychological pressure and test the limits of their endurance.
