Heejun Han is known to be quite the blunt and hilarious guy. Seriously, he could promote as both a comedian and singer at the same time. Both Heejun and Girls' Generation Tiffany were guests on MBC's 'Sunny's FM Date' on May 26, and he gave his very honest opinion on the two Girls' Generation members.

Heejun said, "I had been a fixed guest on Sunny's radio show before. I tried to get closer with her, but it wasn't easy. She surprisingly has a personality that draws a line. But on the other hand, I thought Tiffany would be cold, but she was the complete opposite."

Tiffany agreed as she added, "Sunny is the type to make a clear distinction between public and private matters. Maybe that's why she's been a DJ for so long." Sunny defended herself by saying, "I'm not that cold of a woman. You can't misunderstand me."

Sunny also said, "We're all born in 1989. So that's why I'm really comfortable now. The broadcast atmosphere is really good." Tiffany wittily stated, "But Heejun uses informal language with me and formal language with you." 

Heejun said, "I'm still a little awkward with Sunny. That's why Sunny seems like a sunbae, and Tiffany seems like a fellow Korean-American friend."
