'Heart Signal 3' contestant Kim Kang Yeol has apologized for his physical assault controversy.

On June 5, reports revealed a male cast member of 'Heart Signal 3' was fined for physically assaulting a woman in the past. The alleged victim told media outlets, "In early January of 2017, I was assaulted by one of the 'Heart Signal 3' contestants at a bar in Gangnam, Seoul."

Kim Kang Yeol then confirmed he was the contestant in question, writing on Instagram, "Firstly, I bow my head to the victim and apologize. At the time, my group and the other party had an argument at a drinking party, and it happened in the process of stopping them. My acquaintances and the other party were all women, and there was a physical conflict with each other. At the time, I was too eager to protect my girlfriend, and I made a mistake in the moment when I tried to separate them."

He further revealed that he apologized at the time as well, but the victim wanted to take legal action. Kim Kang Yeol concluded, "It was 4 years ago, and I'm trying to live without repeating the same mistakes. These were also my own actions, and I'm deeply regretting and reflecting on myself again. I will contact the reporter and find ways to apologize to the victim once again."
