Some of the more memorable scenes of '7th Grade Civil Servant' was created using computer graphics.

On February 13th, '7th Grade Civil Servant' released a Behind The Scenes video of the drama on its MBC homepage. The video featured the staff members creating some of the most famous scenes through flashy computer graphics.

According to the video, the banquet hall scene featured on the 3rd episode was filmed in front of a green screen. The green screen was also used for the extravagant office used by Gil Ro (played by Joo Won) that featured floor to ceiling windows with tremendous views of the city. It turns out that the backdrop elements were created through computer graphics and the BTS video showed just a blue wall with a sofa. This has left viewers impressed because the actors realistically acted as if those things were really there.

Another scene that caught the viewers' eye was when Gil Ro romantically proposed to Suh Won (played by Choi Kang Hee) while skydiving. In reality, Joo Won was just hanging on wires in front of a green screen.

Fans who saw this behind the scenes video commented, "I had no idea those scenes were created using CG," "They're really talented I would have never imagined that CG was used," and "I'm seeing it in a new perspective now."

On another note, the February 13th airing of '7th Grade Civil Servant' has intensified the love triangle between Suh Won, Gil Ro, and Do Ha (played by Chansung) and has left viewers wondering how the plot between these three will unfold.
