Super Junior's Heechul opened up about his ex-girlfriend.

On the March 26th episode of '20th Century Hit Song', Heechul and his co-hosts discussed KISS' 2001 song "Because I'm a Girl", and the Super Junior member expressed, "Now that I see it, it's not a love song. It's kind of a curse song. They sing 'I hate that you're doing well.'"

His co-worker Kim Min Ah then said, "That's not the kind of song it is. I think I'd feel kind of jealous too if my ex-boyfriend did too well after breaking up with me." Heechul responded, "I hope it gets better for them. I hope it will always work out better for them, so that they can't say their life was ruined after dating Kim Heechul."
