He had a 'V' app broadcast with his fans where he talked about how frustrated he was at how a webtoon's plot was progressing. A few of his fans who agreed used the term 'the plot is giving me cancer', as it's a popular phrase in Korean to express frustration. Eunkwang saw the comments and said, "Please try to avoid the phrase 'it gives me cancer'. People say that all the time, but it's a really bad phrase."
He explained, "So many people suffer from cancer. Let's think of those people and try to refrain ourselves from using it. We can use better terms. It's better to say things like 'It's frustrating', or 'It makes me angry'. We have to start using better terms to fix things bit by bit."
How considerate of Eunkwang!
