During a recording for MBC Music 'Idol School', while playing the 'Yes or No' game, the statement, "The last time I kissed someone was within the last three months," came up. Some of the idols who appeared on the show stood up to answer 'yes', and UNIQ especially caught attention as several of their members stood up. But Sojin quickly pointed out, "Kissing your members don't count," and hilariously the members who stood up all sat back down. 

When Jun Hyun Moo asked baffled, "Do idol members kiss each other?" Sojin answered for herself as well as on behalf of UNIQ, commenting, "If you put it that way, I've kissed someone within the last three months too since our members kiss each other a lot as we joke around." 

UNIQ's Wenhan and Yibo were also asked to demonstrate, and the two provided quite the fan service as they made it seem almost romantic as Sojin yelled, "No don't make it that intense!" to much laughter.
