In ''Heard it Through the Grapevine" Yoo Ho Jung was startled at the unannounced appearance of Jang Hyun Sung.
In the 6th episode of SBS Monday/Tuesday drama ''Heard it Through the Grapevine" (script Jung Sung Joo, director Ahn Pan Suk) broadcast on Mar. 10th, Han Jung Ho (played by Yoo Joon Sang) and Yeon Hee (played by Yoo Ho Jung) kept on struggling as they had a daughter-in-law who was a minor.
On this day, Jung Ho and Yeon Hee used their strategic plan to bring Bom Yi (played by Ko Ah Sung)'s family to their place. With a dinner featuring both parents at dinner, Bom Yi and In Sang (played by Lee Joon) were nervous. In Sang hugged Bom Yi and said, "This is so that if you hear something hurtful, not to take it personally." Afterwards, the two people welcomed Hyung Shik and Jin Ae. Jung Ho and Yeon Hee regarded their in-laws in the most respectful way, but because they were too polite, it was awkward.
There was a different secret plan. This was to present a proposal to Noo Ri (played by Gong Seung Yeon) as a permanent employee to separate the in-laws from each other.
