Do Yeon, Pinky, Na Young picked Girls' Generation while Yoo Jung, So Mi, and Chung Ha picked 2NE1 as the role models they look up to. Kim So Hye was the only member to name an actress, picking Chun Woo Hee as her role model. So Hye even recited the most popular quote from Chu Woo Hee's recent movie 'The Wailing,' earning a round of applause for her perfectly representing the essence of Chun Woo Hee's character in the film. 

On splitting up after their contract is over on January 31, 2017, Chung Ha said, "I realized that I'm still lacking in many aspects. I want to return to being a trainee, practice even harder, and properly enjoy [my singing career]." Yoo Jung sent a video message to the IOI members ten years from now, saying, "Though we may have disbanded, IOI will always be in my heart." 

I'm sure IOI will always remain in fans' hearts as well! Take a look at IOI's covers of Girls' Generation and performance of "Whatta Man" below.
