In the interview above, the two talked about their first impressions of each other. 

Heejun said, "First off, I was surprised because of how thin you were," He then sheepishly stated, "She came with two hairpins in her hair. Of all the people I've seen wearing hairpins, she's the prettiest."

Tiffany smiled as she replied, "I didn't know you'd be saying this. I should have taken care of how I looked when I came in. Since we were recording [our duet], I originally came in wearing comfortable shoes and just came as is because I initially thought that we wouldn't be filming."

Heejun also gave his two cents on how to tell the difference between a 'some' relationship and dating. He specifically shows the difference, by saying 'some' couples just hold hands, while officially dating couples intertwine their fingers. 

He explained, "The reason is because a 'some' relationship is liking the person's looks and image, and dating is about liking someone for who they are on the inside. That's why they hold hands like that."

Tiffany was very impressed as she asked, "Did you prepare this?"

Heejun laughed as he said, "No I just thought of it now. Usually people who haven't dated know this kind of stuff well."

The two seem to get along very well, leaving us to look forward to their chemistry in their upcoming duet track "QnA"!
