Recently, the conversation of the "Perfect crown" cast revolving around expressing affection has been of interest to the audience.
While Byeon Woo Seok thinks that people should express their feelings of love outwardly to be better, IU has a different point of view.
The 32-year-old actress and singer said: "Real love does not need to be talked about or expressed too much. Love is simply something that exists deep in the heart.
This sharing immediately reminded fans of the relationship between IU and actor Lee Jong Suk.
Throughout more than 3 years of dating, except for the first public relationship post, the two have not shared any other sweet moments together until now.
This is consistent with IU's love view that true love does not need to be expressed outwardly.
However, while the actress's sharing was being discussed, fans discovered Lee Jong Suk's interesting move.
A few days ago, Lee Jong Suk posted many photos on his personal Instagram account without captions. In the photo, he smiles brightly on the road full of blooming cherry blossoms.
In particular, what is noteworthy is the moment Lee Jong Suk creates the image of a bird from cherry blossoms falling on the ground. This character is Tweety Bird - the small yellow bird in the animated film "Looney Tunes".

IU once expressed her love for Tweety and used Tweety's photo as an Instagram avatar for 5-6 years, so the connection between her and this character has become widely known. The female singer also let the bird Tweety appear on the cover of her album in 2024.
Besides, fans recognized Lee Jong Suk creating a mole on his cheek for the Tweety bird, coinciding with the location of the mole of his girlfriend IU.
On online communities, Lee Jong Suk's post quickly spread with the understanding that this was actually a "lovestagram" for IU.
Many people believe that Lee Jong Suk directly creating a character like IU and then posting it is his indirect way of affirming the current strong relationship.
However, some other opinions speculate that the image Lee Jong Suk created is the "Jongduck" golden duck - the mascot representing his fandom and not related to IU.
IU and Lee Jong Suk publicly dated on December 31, 2022, after Dispatch news agency released evidence of their vacation together during Christmas.
The two stars have known each other since 2012 when they hosted the music program "Inkigayo" of SBS.
At the time of confirming the relationship, Lee Jong Suk called it "the result of a prolonged unrequited love"; while IU said they developed feelings during the process of accompanying and supporting each other as long-time colleagues.
After switching from friendship to love, the two still secretly supported his activities. Lee Jong Suk once came to cheer for IU's concert. Conversely, the actress also seemed comfortable when asked about her boyfriend during the promotion of the new movie.
