YoonA shared her honest thoughts about filming 'Confidential Assignment 2: International.' On September 6, YoonA talked with Wikitree and shared her thoughts on filming the sequel to 'Confidential Assignment.'

On this day, YoonA was asked what was the most significant influence on her decision to appear in the second film and explained, "I think it was the family members who appeared. I think it was meaningful because we were together in the second film as well."

It is known that YoonA is a close friend of Son Ye Jin and Hyun Bin married Son Ye Jin this March. Therefore, YoonA was asked if it was uncomfortable having a romantic relationship in the film with the character played by Hyun Bin, who is now Son Ye Jin's husband.

In response, YoonA explained, "In this film, Cheol Ryeong (Hyun Bin's character) didn't become my husband yet, so I didn't feel overwhelmed. I didn't think much about that because the relationship between the two characters remained the same as in the first film. I think it's only a romantic relationship for me," and laughed.

YoonA also explained that she wants to show a more mature Min Young (YoonA's character in the film) if she were to film 'Confidential Assignment 3.' YoonA elaborated, "I think it's more important to keep Minyoung's personality. I think she would be able to show her ability in the third movie since she joined in on the investigation even a little bit in the second film."

When asked about wanting the relationship between Min Young and Cheol Ryeong to become more developed, YoonA explained, "I think it would be good if there is a bit of growth in that aspect too. There were more signs in this second film than the first so I think it would be good if there would be more signals in the third film." She added, "In the third film, Cheolryeong should express something too at that point." 

Meanwhile, 'Confidential Assignment 2: International' follows an unlikely duo - North Korean detective Rim Cheol Ryeong (played by Hyun Bin) and South Korean detective Kang Jin Tae (Played by Yoo Hae Jin) - who partner up with a new teammate, Jack (played by Daniel Henney). These three detectives work together to catch an international criminal while bickering and cooperating without a choice.
