Brian shocked fans all over the world by confessing, "I once thought of committing suicide."

On the May 31 broadcast of SBS' 'Good Morning', Brian opened up about his former idol star days as a member of the unforgettable duo Fly to the Sky.

Brian shared, "While I was promoting as Fly to the Sky, I was on the verge of making a wrong decision due to my emotional suffering. When I was well into my promotions with Fly to the Sky, I received a lot of stress from the loneliness from living in Korea by myself and the emotional baggage that comes with being a celebrity."

Brian was thinking about jumping from the 13th floor of an apartment building he was living in with Hwanhee but he didn't thanks to his fellow Fly to the Sky member.

"At the time, Hwanhee helped me out. I am still thankful to Hwanhee to this day for being by my side to give me strength and watching over me during the difficult time."

Brian also gave more behind-the-scenes stories and a tour of his luxurious home on the episode.
