In the following scene, Yoon Shi Yoon, who has escaped from prison, is disguised in grandma clothing. After seeing Yoon Shi Yoon’s outfit, Jung In Sun jokes, “So there’s really no romance between us?” Yoon Shi Yoon says, “Of course not. It’s over between us now.”

Later, when Yoon Shi Yoon makes a joke, Jung In Sun says to the camera, “I’ve decided to just accept him.” Yoon Shi Yoon says, “You’re no fun. Be tired of me. Be overwhelmed by my energy.”

Jung In Sun says, “He likes that kind of reaction. He likes it so much that I refuse to do it.”

In the next scene, actor Park Jung Hak scares Park Sung Hoon from behind, holding an axe prop and making a scary face. Park Sung Hoon, who has been scared several times by Park Jung Hak already, says, “I got caught on camera getting scared again.”

Getting tied to a hospital bed that’s too small during another scene, Park Sung Hoon comments, “This hurts my pride.” Yoon Shi Yoon seizes the opportunity to poke fun at the actor. He says, “The tables have now turned.”
