"Wonderful Days" Lee Suh Jin captured the relationship between Ko In Beom and Oh Yong.
On the episode of "Wonderful Days" broadcast on April 20th, Dong Suk (played by Lee Suh Jin) called Chi Soo (played by Ko In Beom) to the office.
On this day, Dong Suk asked Kyung Soo (played by Oh Yong) who was the leader of the Investigative Bureau in the Office of the Prosecutor, "Do you know the personal number of Oh Chi Soo?" and Kyung Soo replied, "No, I don't know. There's no reason we would know his personal number. I called through his secretary last time too" he replied.
At this, Dong Suk asked to talk on the phone and said, "Then call the secretary and ask where Oh Chi Soo is and when he'll arrive."
As Chi Soo arrived in the office, Dong Suk secretly called Kyung Soo and called Chi Soo and Chi Soo's phone rang soon. Kyung Soo who claimed not to know Chi Soo's personal number was startled.
Dong Suk shouted, "Do you know how important it is that the investigator is bribed?" Chi Soo refuted saying, "Are you taking something so petty to link me to him".
However, Dong Suk ordered Chi Soo to be pressured saying, "In my desk is proof that Oh Chi Soo sent $300,000 to relatives of Park Kyung Soo. Investigate into Park Kyung Soo and Oh Chi Soo's phone records."
