He revealed to the interviewer, "I was very disappointed that there weren't any romantic scenes in 'The Attorney' and in 'Misaeng'. It's unnatural to force a romantic lead where there aren't any, and it's also wrong to do so. Personally, it would be best for me to have a lot of melodramatic scenes. I just like romance, but that's separate from cinematic quality."

Siwan also revealed that while the four interns have a kakaotalk group chat, they communicated a lot more on the set than online. He said, "There were more times when we would talk face to face."

Meanwhile, viewers initially speculated a possible romance between Kang So Ra and Siwan as they were seen helping one another out during their intern days. However, the scenes between the two decreased throughout the drama as it focused much more on the dynamic among the four interns and the different sales teams.
