In "Bluebird House" Lee Sang Yeop argued with Chun Ho Jin and said that Lee Joon Hyuk must be innocent.
On the episode of "Bluebird House" (script Park Pil Joo, director Ji Byung Hyun, producer, Hidden Pictures Media) broadcast on June 7th, Jang Tae Soo (played by Chun Ho Jin) put Kim Ji Wan (played by Lee Joon Hyuk) in a corner.
On this day, Kim Ji Wan tried his best to rid himself of the rumor that he was a corporate spy. Before this, Kim Ji Wan took the designs for the new products to a meetings where the overseas buyers were coming. Nonetheless, Jang Tae Soo made it so that there would be no choice but to lose the product design.
Kim Ji Wan heard from Jang Hyun Do (played by Lee Sang Yeop) that there would be an alarm if the product design's security chip was sent outside the building. Kim JI Wan said, "But that means that the design might still be inside. What if there was an internal collaborator?"
Afterwards, Jang Hyun Do was having dinner with his family members when he was talking with Jang Tae Soo. He said, "If that's not the case, there's just simply not enough time to take the chip out of the design. Someone must've done this where the CCTV doesn't reach."
