On Thursday, tvN "E! News" released the behind-the-scenes of Seo In Guk and Jung Eunji's fountain kiss scene. Seo In Guk prepared the kiss scene by doing push ups and Jung Eunji started gargling her mouth after saying "I have nothing to prepare. I'm the one being kissed."

Jung Eunji had to kick Seo In Guk when he kisses, but as he actually kissed Jung Eunji showed her shyness, saying "When do I have to kick him?"

After 16 times of NG, the 'Fountain Kiss' came to be. Internet users replied "Please show more NG scenes," and "I can assume that the set vibe is very friendly."

On the other hand, "Respond 1997," which centered around six girls and boys with the 90's Busan background ended with great love from the viewers.
