The idol guested on the April 11 episode of '1 vs. 100' and revealed that she feels the age difference with her members. She said, "I feel it when I don't know the abbreviated terms. I also tend to be late in watching (viral) clips." 

However, she explained that there aren't any problems when having conversations with them. 

Sojin continued, "Maknae Hyeri and I have an age difference of 8 years. In the beginning, it was alright because I was young too but as time goes I get worried about looking different than my dongsaengs." She also revealed, "Unlike the dongsaengs, I wasn't prevented from dating when we first debuted."
