In "Remember You" Suh In Gook accepted the request to collaborate on Jang Nara's investigation.
On the 2nd episode of KBS 2TV Monday/Tuesday drama "Remember You" broadcast on June 23rd, Lee Hyun (played by Suh In Gook) agreed to participate in the investigation of Cha Ji Ahn (played by Jang Nara).
On this day, Cha Ji Ahn went to the classroom of Lee Hyun and asked for help on the investigation. She said, "I'm your fan. Please collaborate as a type of fan service. Think about it. Just think about it for three seconds." With that, she followed him around.
In the end, Lee Hyun took in the investigation request. He then revealed that the murder incidents in Bangbae-dong and Dohwa-dong were murders that had been planned and were predictable. Lee Hyun said that in each of the scenes, there were purple flowers at the murder scene.
Afterwards, Lee Hyun said, "When I went to the scene in Dowha-dong, there's something I couldn't understand. This was a criminal that didn't want to leave any harm. But then again he used merciless violence on the second victim. Why is that? That's probably because he couldn't hide his sudden anger." With that, he talked further about the incident.
