On the January 21st episode of Mnet's 'Beatles Code 2', singer Seo In Young confessed that she dated a celebrity in the past, raising the curiosity of viewers as to who the mystery man is.

When asked if she's ever dated someone famous, Seo In Young answered honestly, "I've only dated one [celebrity]," which led the MCs to dig further for details about the relationship. They asked, "Singer or actor," but she hesitated to answer.

The MCs were quick to realize why she was speechless and asked, "Is he both a singer and an actor?" Seo In Young silently nodded her head.

She also opened up about her first kiss, sharing, "I don't remember my first real kiss. I had my first peck in the second year of middle school. During recess, I pecked a school sunbae oppa."
