In "Heard it Through the Grapevine" Yoo Ho Jung was putting an amulet in Ko Ah Sung's room. As she caught her, it was amusing to find Yoo Ho Jung trying to make up excuses.

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, Choi Yeon Hee (played by Yoo Ho Jung) and her secretary Lee Sun Sook (played by Suh Jung Yeon) put an unidentifiable amulet on Suh Bom (played by Ko Ah Sung)'s room.

At that moment, Suh Bom barged into the room. Choi Yeon Hee was surprised and asked why she didn't knock. At this, Suh Bom said, "Well it's our room" as she was startled. Listening to this, Lee Sun Sook said, "It's an old tradition. It's so that the ancestors will wish well for the descendants" and muttered.

At this, Suh Bom said, "Is it like an amulet" as she asked further questions. At this, she told Choi Yeon Hee, "Please tell me next time before you enter my bedroom." Choi Yeon Hee said, "I made a mistake while trying to keep a family tradition." At this, Suh Bom said, "I don't think it's a great tradition" and startled Choi Yeon Hee.
