BTOB's Changsub once again denied the dating rumors involving Jung Jae Eun.

On the January 8 airing of MBC Every1's 'Video Star,' Changsub explained the dating rumors with the musical co-star that surfaced last summer. 

The dating rumors stemmed from a video of Jung Jae Eun linking arms with Changsub. 

The idol star explained, "We're really just close colleagues. That day, we met to talk about our musical and while going down the steps, she said she was scared so she held onto me."

Fellow guest Se7en commented, "I have also worked with them. The three of us are really close. I wasn't there that day but they became awkward because dating rumors surfaced in midst of the show period," and emphasized, "I didn't catch any strangeness between them."

Changsub assured fans, stating, "I know my fans were very surprised. We are just close sunbae-hoobae. You can stop thinking about it. I'll return after doing well in the military."
