Singer-turned-actress Eugene spoke about S.E.S' past rivalry with Fin.K.L. The first generation idol of the famed '90s girl group appeared on the April 25th broadcast of MBC's 'Knee Drop Guru'.

She looked back on her days as a member of S.E.S. and said, "We were kind of rivals with Fin.K.L. They were always on our mind. We kept wondering about what type of people they were and what song they would release. I saw the music video to their debut song 'Blue Rain' and thought that it was really good. But I also felt that they weren't better than us," making Kang Ho Dong laugh.

Eugene went on to say, "I felt that their song was good, but our song was better. I thought to myself, 'Maybe they will become our rivals?' To be honest though, they did have better a better wardrobe than we did."
