In "Heard it Through the Grapevine" Yoo Joon Sang could not hide his anger after a clump of his hair was pulled out.

On the 7th episode of SBS Monday/Tuesday drama "Heard it Through the Grapevine (script Jung Sung Joo, director Ahn Pan Suk) broadcast on Mar. 16th, Han Jung Ho (played by Yoo Joon Sang) started to insult his daughter-In-law Suh Bom (played by Ko Ah Sung) about her family in front of her.

Hyung Shik (played by Jang Hyun Sung) wanted to stop Jung Ho from hitting In Sang but the two only ended up getting into a fight. In the end, the two family turned their backs on each other and went their separate ways. In addition, Jung Ho had been very sensitive about his hair loss and was angered that so much of it was plucked.

At this, Jung Ho sat down In Sang and Suh Bom to lecture them. He said, "I'll tell you what your parents' problem is. They don't know an opportunity when they see one. That's why they can't get out of poverty." This was because he was angered that Suh Bom's parents didn't take in the suggestion of farming life. With that, he insulted Suh Bom's family.
