Ha Sung Woon talked about his close friend BTS' Jimin. 

On the March 26 airing of MBC FM4U's 'Kim Shin Young's Hope Song at Noon,' special DJ Park Sung Kwang said, "I heard you went to coin noraebang (karaoke) with BTS' Jimin during your break." 

Ha Sung Woon replied, "Yes. It was during the holiday. I somehow went to Ilsan. I was on my way to go seeing my dad, and I ended up being with Jimin somehow. There was a coin noraebang on the way, so we stopped by."

He continued, "We sung the song titled 'Stalker.' We also sang several other songs, but I can't remember."
