The producer said he didn't expect Cha Eun Woo and Dahyun to receive so many votes during the pairing selection process. He explained, "For Eun Woo and Dahyun, a lot of fans in their teens left various replies. As a result, we ended up with what you'd expect, a high-teen drama. Of course, there's suffering and hardship too. A lot of replies wanted the two to fight as if to make them drift apart, even suggesting one to move to keep them from becoming closer."

He also added, "It's supposed to be a romantic comedy, but it was a little difficult to keep it that way sometimes. Nonetheless, Dahyun said, 'It's the most I've laughed in a while,' after we finished filming."�

The producer concluded, "In Eun Woo and Dahyun's skit, there is a cameo. Several replies asked for this cameo, so we recruited them. Please anticipate who it could be."

'Replies That Make Us Flutter' starring, not only Cha Eun Woo and Dahyun but also Heo Kyung Hwan, Noh Min Woo, Joo Woo Jae, and Moon Ji In, airs September 15 at 11PM KST!
