(If you read chapter number 21 then this is the connection and negotiation between Gong Tae Joon and Jeon Na Ra after Kim Yoon Gi's return.)
Na Ra sees Kim Yoon Gi's car coming out of his yard, the man says if he has to meet someone else, Tae Joon doesn't let him at first, but the man has quite an intensely busy life.
And Tae Joon also thinks that if Yoon Gi is not a man who will be able to sleep well, if his work is not finished, and does not calm him down, then the man will be busier and unable to sleep and get rest in his sleep.
"You believe him?" asked Na Ra making Tae Joon nod his head slowly, the man still looked at the closed gate with a sad and confused look too. "Let's talk, Na Ra," Tae Joon asked his wife to follow him.
The two of them walked to the previous place, a copy of the previous evidence even Yoon Gi deliberately stayed because Yoon Gi knew that Tae Joon and Na Ra would think about it both and in a friendly manner.
