On the 25th episode of tvN's "Amazing Saturday," an incident occurred where Park Na-rae betrayed her team for Baekho. Baekho, Lee Chan-won, and Hwang Yoon-sung appeared on the show that day. Park Na-rae revealed the reason behind her transformation into a pure and innocent look. Boom mentioned, "The reason for dressing up is because of Baekho. As soon as his visit to 'Amazing Saturday' was confirmed, it started with makeup and hair," adding that it was all fake.

Park Na-rae shyly looked at Baekho while fiddling with her hair, and Baekho said, "This is the first time I've seen your face. You hardly look this way." Park Na-rae explained the urgent situation, saying, "There have always been makeup accidents. I was originally going to do 'Mr. Bean,' but the main writer contacted me urgently. He said, 'You have to look pretty today. That person is coming out.'" Park Na-rae confessed to Baekho, "I really like 'Elevator.'"

Boom suggested a role-play, saying, "A scene where they accidentally bump into each other on campus and fight." Park Na-rae questioned, "Why are we fighting?" Baekho, fiddling with his watch, wondered, "Should I undo my watch because they told me to fight?" Park Na-rae pretended she couldn't walk because of an ankle injury, and Baekho carried her. Park Na-rae shouted, "Thank you, 'Amazing Saturday,'" and said, "I'm not taking a fee today."

In a pre-interview, Baekho mentioned that there was something about Park Na-rae that caught his interest. Park Na-rae showed anticipation, but Baekho said, "I've watched you work for a long time. It's related to today's outfit, but your trapezius muscles are exceptional." He added, "This is the real V-taper, with a depth and thickness that doesn't come easily. I kept wondering how you built it." Park Na-rae expressed disappointment, saying, "Is the only thing you want to ask me about my trapezius muscles?" Baekho admitted, "Actually, yes."

Park Na-rae showed off her muscles, saying, "Don't people all do pull-ups at home?" Baekho admired, "This thickness doesn't come easily. You really work out." Then Park Na-rae wiped Baekho's sweat, and Hanhae commented, "They both sweat a lot, too." Moon Se-yoon said, "It's like a really funny skit," making everyone laugh.

Later, during team selection, Baekho looked at Park Na-rae and handed the bouquet she was holding to Hanhae. Park Na-rae attacked Hanhae, angrily saying, "Because of you. Did you ruin my future?" Baekho confessed, "If I failed, I thought I'd get scolded by her. I thought I might be physically overwhelmed, so I chose Hanhae to survive."

In the team game, just before Park Na-rae was about to answer a question, she listened to Baekho's plea and betrayed the team. Key warned, "If this affects the outcome, I won't stay still," and Nucksal joked, "Then I'll really kick you in the butt," making everyone laugh. Before the last question, Park Na-rae declared, "There's a 7-year loyalty," promising not to betray, but she ultimately betrayed again and was dragged out.

This episode provided great entertainment to viewers with the cheerful chemistry between Park Na-rae and Baekho and the tension of team betrayal. After the broadcast, viewers showed various reactions to Park Na-rae's transformation and her interactions with Baekho.
