Former "Produce 101" trainee Jung Joong Ji has accused Wanna One's Yoon Ji Sung of bullying when they were still contestants on the show. The claim first surfaced in the summer, when someone posted on the internet that Joong Ji talked about Ji Sung when he/she met with Joong Ji at a church in Gwangju. Joong Ji said Ji Sung was a bully who frequently discouraged him.

However, the claim backfired as people accused Joong Ji of being "fake." They pointed out that Joong Ji once posted a selfie with Ji Sung while talking bad about him behind his back. Following criticisms toward him, Joong Ji now explains the situation in a lengthy message posted on Instagram on Thursday, November 2.

"You asked for feedback. I wasn't going to but here it is," he begins his post. "There was a time we ate together for the first time during 'Produce 101 season 2'. There, Yoon Ji Sung hyung suddenly called me over and said, 'You have a lot of followers on Facebook. You should make money with that. Why the hell are you here?' So I replied, 'I'm sorry, hyung.' After that, he kept bothering me about 10 times so I told him that he's really making it hard for me and to stop bullying me. He smiled and said 'okay', and then told me three trainees in his agency had left because of him."

He continues, "Then on the day when we had the level test, I only slept for an hour due to ongoing practice and messed up almost entirely during the actual test so I was sitting down with a frown on my face, and he came over and teasingly said, 'You just did your worth.' I was so startled and in disbelief (at his rudeness) so I talked back to him. But after some time, we made up and that's why I uploaded the photo (selca)."

"Some are asking why I talked about Yoon Ji Sung hyung at the church when I wasn't even asked about him but the thing is I just answered what they asked me. I wasn't talking behind his back. I was just answering their questions. I told them what happened because they asked me. I also told them we made up after time," Joong Ji explains.

He further shares, "But it's unbelievable how there are people telling me to stop lying. Why would I make up such stories? Do you think I'll be making this up because I want to get sued? At the time, I even told the producer and we made up later on. And that happened with me offering bread to him, because he said he was hungry. We were all very hungry at the time, and I offered mine to him, and he said, 'You eat it first. Did you mix something in it?' so I said 'no', took a bite first, and then gave it to him."

"No matter what anyone says, I am not lying. No matter who believes me or not, I just wrote the truth with a hand over my heart. No matter who criticizes me or not, I'm not afraid because I wrote this truthfully. A lot of words will be circulating due to this but people keep telling me to stop lying and that's making me feel suicidal so I'm leaving this long message," he claims, before telling people, "Also, stop sending me direct messages. I'm a human, too. Stop tormenting me."

Yoon Ji Sung, who finished eighth on "Produce 101" season 2, debuted as a member of Wanna One in August along with ten other members.
