In ''Heard it Through the Grapevine" Yoo Joon Sang showed two different sides. Ordinarily, he was very stern but in the evenings, he would sneak out and see his grandson as his love for his grandson could not be hidden.
In the 6th episode of SBS Monday/Tuesday drama ''Heard it Through the Grapevine" broadcast on Mar. 10th, Han Jung Ho (played by Yoo Joon Sang) awoke in the middle of the night without his wife Choi Yeon Hee (played by Yoo Ho Jung) knowing.
Because he didn't want Choi Yeon Hee to wake up, he was walking on his tippy toes and started going to another location. The place that he arrived was none other than the room of his grandson. Yoo Joon Sang saw his grandson sleeping. He was extremely excited seeing his grandson sleeping. With his awkward hands, he held the baby in his arms and was very happy.
Nonetheless, seeing Han Jung Ho go into the room, Han In Sang (played by Lee Joon) followed him into the room. Han Jung Ho had a stern face saying, "If you made a rule, shouldn't you be keeping it? Should you really be doing this?" as he was serious.
