In "Heard it Through the Grapevine" the past relationship of Baek Ji Yeon and Yoo Joon Sang was drawn out as Yoo Ho Jung was annoyed by Yoo Joon Sang's attitude.

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) met the husband of Ji Young Ra (played by Baek Ji Yeon) regarding an accounting audit issue.

As secretive conversation went back and forth, Ji Young Ra said hello to Han Jung Ho. She said, "I want to introduce you to a hair clinic for hair loss. Yeon Hee was worried these days saying that it's been severe." With that, she annoyed him.

The two people reunited in a secret place again. Ji Young Ra kept on asking Han Jung Ho to conceal her husband's crime. Han Jung Ho said, "You're the same when it comes to nagging. Don't say unnecessary things to my wife. Let's separate our work life and our personal life. Pick one thing. Whether it's going to be the probation of CEO Jang or whether it'll be fines of your father." He cut her off.
