On the May 17 airing of JTBC's 'With You,' IOI made an appearance to interact with Kim Sook and Yoon Jung Soo, who visited the girls' dorm! �Also, their dorm seems very nice.

On this day, Kim Se Jung said, "I'm famous for looking like Kim Sook," but she replied, "If you stand next to me, you don't look like me."

However, Yoon Jung Soo said, "It looks like Kim Sook gave birth to Kim Se Jung." �Kim Sook said, "If I had married early, I really would have a daughter this big," causing laughter. Perhaps there's a K-Drama family twist here?!

Do you think they look alike?
