On April 23, the cast participating in the Korean drama "Perfect crown" (or "Wife of the 21st Century Army") including IU, Byeon Woo Seok, Lee Yeon and Yoo Su Bin appeared together on IU's YouTube channel, sharing behind-the-scenes stories during filming.
The 4 actors became close during the production process, so the atmosphere of conversation was very cheerful and lively. When getting into the role, they also divided into small "teams" according to the characters, showing harmony on screen.
In the conversation, Byeon Woo Seok recalled a scene with Yoo Su Bin that did not go as smoothly as expected. Yoo Su Bin explained that the scene was filmed in a later stage, when they became closer, so he felt the pressure to perform better. Byeon Woo Seok added: "Because we cared more, the emotions were also stronger".
Hearing that, Lee Yeon joked: "So that means there was little love at first, right?". IU immediately gave a deep perspective: "That's right. And if it's true love, you won't feel the need to talk about it or express too much.
She added: "Love is something simple that exists deep in your heart", expressing calmness and experience.
After a short pause, Byeon Woo Seok shared his point of view: "Lately, I think expressing love outside is a good thing." Yoo Su Bin immediately said: "I love you", making the whole studio laugh.
Byeon Woo Seok also quickly replied: "I also love you", once again emphasizing that love should be expressed openly.
Although it was just a fun conversation between the actors, IU's shares caused discussion, causing viewers to associate her relationship with actor Lee Jong Suk.
IU and Lee Jong Suk publicly dated on December 31, 2022, after Dispatch news agency released evidence that the two were vacationing together during Christmas vacation.
The two stars have known each other since 2012 when they co-hosted the music program "Inkigayo" of SBS.
When confirming the relationship, Lee Jong Suk called it "the result of a prolonged one-sided affection"; while IU said they developed feelings in the process of accompanying and supporting each other as long-time colleagues.
In more than 3 years of dating, except for the first public post, IU and Lee Jong Suk have not actively shared any more sweet moments until now.
They did not post photos together on social networks, instead they only secretly supported each other's activities. Typically, Lee Jong Suk came to cheer for his girlfriend's concert, or IU mentioned her boyfriend during a movie promotion.
Because the couple did not reveal any signs of affection, they were repeatedly suspected of breaking up.
Recently, rumors that IU and Lee Jong Suk are no longer together have spread again, but neither of them has spoken out to explain or confirm.
