Actress Choi Jin Sil had committed suicide in 2008, leaving behind her young son Hwan Hee and daughter Jun Hee. The tragedy had shaken Korea, and it became even worse when her brother also committed suicide in 2010. However, in 2010, Swings had featured in a track by rapper BIZNIZ titled "The Uncomfortable Truth". Truth is 'jin-shil' In Korean, and Swings had rapped, "The uncomfortable truth (jinshil)? You guys are Hwan Hee and Jun Hee. There's no truth (jinshil), just you guys."
The lyrics had been met with incredible criticism, with listeners demanding to know if Swings was in his right mind to use such a tragedy in his rap and even disrespect the family and children. Swings had apologized for the usage and said it was not his meaning to disrespect or hurt the family, and faulted himself for not fully putting himself in the family's position.
However, the song suddenly came back into focus on SNS lately. When Choi Jun Hee saw the lyrics on Facebook as well as the controversy, she commented on it angrily, saying, "I'm sorry, and I know it's wrong to bring up the past, but the people that have to live with the hurt are me and my brother. I honestly can't understand how people can say it's all in the past. I don't watch 'School Rapper' because of Swings, and I don't watch most rap-related things. I get so mad whenever I see him, and in his apology he said he didn't know it would be painful. Back then, I didn't know because I was young, but if I think about it now, isn't it just ridiculous from my point of view and my family's point of view? Even if it's in the past, the anger and pain remain the same. If you ask why I'm still mad, it must be because you've never thought from my point of view, right?"
Netizens are furious at the lyrics and are demanding that Swings step down from all shows, even if it's something that happened in the past.
