On September 14, a short clip of DEX greeting someone was released on a YouTube channel, '117'.
He has been hosting his show, 'DEX's Fridge Interview' on the channel since last February.
After a successful first season, the channel has announced that the second season will premiere on September 21.
The channel released a short preview of the show's first episode, in which the host, DEX looked giddy from the very beginning.
Before meeting the guest, he punched the air with excitement and took a deep breath, shutting his eyes tight.
DEX has repeatedly mentioned SANA as his celebrity crush.
After introducing the day's guest to the camera, DEX stiffly greeted SANA.
When their eyes met, he glanced away from SANA and said, "I just can't look at her."
At one point, SANA said, "I've watched your show, and you've never seemed that stiff before.", sweetly giggling.
DEX burst into laughter and cried, "I'm sorry!"
"I guess I got a little nervous. I tried to hide it, but yeah, I'm nervous.", he finally said.
"When people ask me who my celebrity crush is, I always answer that it's SANA of TWICE.", he said.
He revealed that he became SANA's fan seven years ago, after seeing her on TV for the first time when he was in the military.
"About the time she just made her debut, I enlisted in the military and saw her for the first time in the recruit training center. At one religious event I attended, a Buddhist chaplain said, 'Now, we will enter the visual nirvana.', and then played TWICE's music video. It was eye-opening.", said DEX, adding that that was the time he got a crush on SANA.
