Kwanghee revealed why he felt betrayed by fellow ZE:A member Siwan.

On the September 16th episode of YouTube series 'Pinggyego', Kwanghee and Siwan featured as guests, and Kwanghee revealed he's been studying English lately. When asked if he wants to promote globally, Kwanghee shared, "I have a habit of always calling Siwan and trying to teach him something. Siwan knows that, but he takes it well."

He continued to explain that Siwan hadn't told him a major piece of news, saying, "Last winter, I told him, 'Get ready to go abroad. Study English.' I was embarrassed because I then saw an article about him starring in 'Squid Games 2'. He stayed quiet even though he knew."

When asked why he stayed quiet, Siwan said, "I was restricted from talking about it."
