”What would you do if you were to take a photo?” Meeting with DinDin and Mijoo's sister... ”Facial expression that gives you a free pass to the interview”

On the 6th at 6:30 pm on MBC's "What Would You Do If You Were Filming?", DinDin was shown meeting Mijoo's (former LOVELYZ) sister.
On the show that day, DinDin asked Yoo Jae Suk, "Have you seen Mi Joo's real sister?" and Yoo Jae Suk replied, "I haven't."
DinDin responded with a laugh, "That's great." So, Yoo Jae-seok decided to call Mi-joo's sister and said, "I know that DinDin was interested in her.
Mi-joo's sister replied, "I knew," and Yoo Jae-seok asked, "How did you feel when you heard that story?"
Mijoo's sister then said, "Well, I thought that was only natural," drawing laughter.
Mijoo panicked and said, "She's crazy," and told her to hang up. Yoo Jae-suk responded, "After that, the staff called her again, but she had already appeared on the show.
Lee Yi Kyung asked, "Does your sister live in Okcheon?" Mi Joo replied, "I'm originally from Daejeon.
"I live in Daejeon, but today is my day off," she said. Yoo Jae-suk asked, "What do you do for a living?" and Mi-joo replied that she was a dental hygienist.
After that, DinDin met Mijoo's sister. DinDin said to Mijoo's sister, "You have a face that gives you a free pass at interviews," and "Unlike Mijoo."
Mijoo asked, "Why are your ears so red?" and "Who is prettier, me or your sister?"
Then DinDin said without a second thought, "Your sister is prettier."
Yoo Jae-suk said, "Mijoo sometimes talks about her sister," and asked, "What kind of sister is Mijoo?"
Mijoo's sister responded, "She's unsociable, but she's trying to be nice.
In response, Mijoo said, "Seeing my sister, I realized that I have to be kind to my parents."
The quarrel caused laughter.
