In "Heard it through the Grapevine" Kim Kwon decided to retire in order to go up against Yoo Joon Sang.
On the 26th episode of SBS Monday/Tuesday drama "Heard it through the Grapevine" broadcast on May 19th, Han Jung Ho (played by Yoo Joon Sang)'s authority started to shake up.
On this day, Yoon Je Hoon (played by Kim Kwon) said that he would quit the company in order to launch a lawsuit against Han Song. Han Jung Ho said, "Don't you worry about you father? You can always be fired you know" and suddenly threatened him.
However, Yoon Je Hoon said, "I told you and he understood" showing a very strong will. In the end, Han Jung Ho took in this thought and said, "I will keep thinking about it."
Afterwards, Han Jung Ho listened to words of Yang Je Hwa (played by Kil Hye Yeon). Before this, Yang Je Hwa said to Han Jung Ho, "Not everyone admires Han Song. It's not that everyone is afraid of the executive either though. I'm trying to change." With that, he put out a very strong criticism.
Meanwhile, "Heard it Through the Grapevine" is about the wealth and greed of the high society that permeates in South Korea with its lofty yet materialistic ideals.
