On the December 17 installment of MBC's 'Radio Star,' B1A4's Baro and GOT7's Jackson appeared for a youthful and entertaining episode.  

Jackson said, "I came to Korea to do music, so I don't think I should be dating right now," which made the MCs curious about his ideal type.  He replied, "I like women with dark complexions.  My ideal type is Song Ga Yeon.  There was even a time I talked to her.  Actor Seo Kang Jun asked her in my stead, and she replied, 'I don't see Jackson as a man at all,'" making everybody laugh.  

The MCs also threw at Baro, "I heard you're not that close to Jackson, but Jackson acts like you are."  He replied, "We became closer when we came here today."  

Jackson quickly said, "We were always close," but Baro said, "We shot a uniform CF together.  Whenever he talked to me, he kept saying he felt a connection with me and wanted to become closer, but he said that to everybody, so...." explaining that was why he felt disconnected from him. 

Jackson again defended himself with, "I thought we were close even before that."  Baro replied, "Sorry.  Truly," making everyone laugh.

In addition, just the other day, Jackson protested on 'Roommate' that J.Y. Park was harsh towards him but amicable towards Suzy, which he brought back up on 'Radio Star' this day, even showing the difference in attitude by personally acting it out.

He showed how Suzy would greet J.Y. Park with a sweet, "Oppa, I'm here," and he would reply brightly with a, "Hi Suzy!"  The amused MCs replied "From a manager's viewpoint, the profits... Suzy is a walking enterprise."
