In "Heard it Through the Grapevine" the fixation that Yoo Joon Sang had for Baek Ji Yeon created a situation where people could not laugh.
On the 16th episode of SBS Monday/Tuesday "Heard it Through the Grapevine" (script Jung Sung Joo, director Ahn Pan Suk) broadcast on Apr. 14th Han Jung Ho (played by Yoo Joon Sang) was lured by the temptations of Ji Young Ra (played by Baek Ji Yeon) and gave her a call.
Han Jung Ho said to Ji Young Ra, "I was working without sleep and I needed a place to lie down." With that, Ji Young Ra was surprised and said, "Are you crazy?" Han Jung Ho was startled and said, "Are you upset? Then forget about food but let's just see each other for a bit. Tell me the intersection where you're standing" he begged.
Nonetheless, Ji Young Ra said, "I have to have dinner at home and take my sibling to the airport." Nonetheless, Han Jung Hos said, "But the routes will cross. I'll call back later" and picked up Choi Yeon Hee (played by Yoo Ho Jung)'s phone call.
Choi Yeon Hee had a video call with the grandson Jin Young and Han Jung Ho said, "I have a really urgent call so let me hang up and call again."
