"Gu Family Book" Lee Seung Gi and Bae Suzy seem just like a couple on and off the set of the drama.

May 28, an episode of the MBC drama "Gu Family Book" featured Choi Kang Chi (Lee Seung Gi) and Dam Yeo Wool (Bae Suzy) flirting with each other throughout the day then going on a date together later that night. They stared into each other's eyes with great love in their eyes. They were also shown making a lot more physical contact now.

Even though Dam Yeo Wool was ordered to stay inside the whole day, she escapes by tying up the person who had been keeping watch after hearing news that Gong Dal had been killed. As soon as Dam Yeo Wool sees Choi Kang Chi, she asks, "How did you end up there when it happened? Everyone is going to think that you are the one who did it. Did father scold you?" Choi Kang Chi smiles as Dam Yeo Wool's concern for him. Even though everybody else blames him for the murder of Gong Dal, Dam Yeo Wool stays on Choi Kang Chi's side and worries about him getting blamed.

Choi Kang Chi worries about Dam Yeo Wool's health since she had injured her ankle. He says, "You can injure it more easily after injuring it once. Don't run again and be careful."

They both enjoyed each other worrying for each other. Dam Yeo Wool says, "You are becoming so bossy these days. You seem like a man these days." Choi Kang Chi replies, "Do you like it? Your two eyes tell me you like it to death."

Later that night, Choi Kang Chi and Dam Yeo Wool meet again. Choi Kang Chi waits her Dam Yeo Wool to sneak out again to go on a secret date together. Choi Kang Chi grabs onto Dam Yeo Wool's hand and tries to kiss her for the first time. However, the moment is ruined when someone appears looking for Choi Kang Chi.
