In "Bluebird House" Lee Sang Yeop was deep in contemplation about what to do with the secret bank accounts of Segi Bank. In the end, he decided not to steal this Item.

On the 40th episode of KBS2 weekend drama "Bluebird House" broadcast on July 5th, Tae Soo (played by Chun Ho Jin) fired Ji Wan (played by Lee Joon Hyuk). Hearing about this news, Young Joo went over to Hyun Do and asked Ji Wan to help. Hyun DO was deep in contemplation and felt conflicted.

Afterwards, he went to Tae Soo's office and opened the safe. He was looking at the bank records for a while but left it there. A bit later, Tae Soo entered. Hyun Do said, "Why did you do this, dad? Even if you didn't do this, wouldn't someone of you're abilities be able to create a company as grand as this?" With that, he felt unfortunate that this had happened. He then said, "At the end of the day, I'm really your son, dad." With that, he walked away without any energy.

After Hyun Do left, Tae Soo felt that things were a bit strange. He opened the safe but inside the safe was the notebook fully intact.
