The First Night with the Duke is one of the most popular Korean dramas. Because the film is adapted from a famous online comic book before, it has had a certain number of fans, especially young audiences.
On the other hand, when the film aired, the chemistry between the main couple, the two famous 2nd generation Kpop idols - Seohyun of SNSD and Taecyeon of 2PM - attracted more Kpop fans.
Despite only releasing the first episodes, the good acting of Seohyun and Taecyeon on screen quickly caused a stir among Kpop fans.
Notably, in the recent episode, Taecyeon - Seohyun's kiss scene received a warm reaction on social networks.

Many audiences expressed that seeing two famous idols in romantic scenes made them feel unreal and like a dream. The audience added that this was unimaginable at the peak of their idol careers.
If this scene had been broadcast 10 years ago, it would have caused great chaos and controversy. Taecyeon is an idol member of 2PM - an audience commented, recalling the enthusiasm of the Kpop fan community in the past.
Other comments also said that watching Seohyun and Taecyeon's movies reminded them of the peak period of activities of the two top 2 generation Kpop groups.
"It reminds me of year-end stages and advertisements on Caribbean Bay (SNSD and 2PM's joint advertisements), "It felt like a space collision", "It's unbelievable that I'm alive to see this", "If it was the idol era, this would be unimaginable", "They caused a stir when performing together at year-end stages, and now they even have a kissing scene" - some outstanding comments.
In addition, many audiences mentioned another couple of the two groups, YoonA (SNSD) and Lee Jun Ho (2PM), when the two collaborated on the romantic film "King The Land" in 2023.
At that time, YoonA - Jun Ho's chemistry exploded to the point that they were voted as one of the most beautiful on-screen couples of the year and were suspected of dating.

The combination of veteran idols on screen has repeatedly surprised the audience.
Some opinions say that in the second generation of Kpop, idol groups have fierce competition, but there are also interesting relationships between them, not completely separating between men and women like today's idols.
Many members of different gender music groups still maintain good relationships until now. SNSD and 2PM are examples. That is the reason why fans miss them when they see them become co-stars in the film industry.
