On March 26 episode of KBS' television show 'Hits Song', HeeChul talked about his ex-girlfriends.
HeeChul explained, "The song goes, 'I don't want things to go well for you. Why are you happy with that pretty girl?' It kind of puts a curse on exes."
Kim Min-ah responded, "Well, but don't you feel annoyed if things go too well for your ex-girlfriends after breaking up with them?"
HeeChul commented, "If, by any chance, things go badly for them, I don't want people to say their lives were ruined because they dated me."
He continued, "So, I'm always hoping they'll do even better and succeed even more than they were before."
