IOI Jeong Chaeyeon’s hidden drinker side: “I can’t see her drunk 모습,” Choi Yujung drinks a glass of somaek (cheers), (One decisive moment)

Singer and actress Jung Chae-yeon was named as the hidden heavy drinker of the group I.O.I.

On May 18, a video featuring former I.O.I members Jeon Somi, Choi Yoojung, Kim Chungha, and Yoo Yeonjung as guests was uploaded to the channel "Ssalhanhyeong Shin Dong-yup."

That day, Yoo Yeonjung mentioned Jung Chae-yeon, saying, "Among I.O.I, there is someone whose drinking capacity is the highest." Yoo Yeonjung said, "She even likes straight liquor. I've never seen my sister get drunk first."

Jeon Somi also mimicked her, saying, "(Chae-yeon unnie) speaks in a very refined way," and, "If you say let's drink baijiu, she'll go, 'Hmm~ Someone who can go from baijiu to vodka?'" drawing laughter.

Yoo Yeonjung said, "At practice, everyone dresses sloppily, but unnie comes in wearing sunglasses and a trench coat and says, 'Hey, guys, hi,'" sharing Jung Chae-yeon's uniquely elegant and demure side.

Choi Yoojung appeared tipsy after just one glass of somaek. Choi Yoojung, who got drunk at lightning speed, awkwardly asked, "Please don't focus on me." Yoo Yeonjung said, "After she suddenly gets drunk and rests for a bit, she comes back to normal again," and added, "If we hang out like that until dawn, she stays until the end."
