The couple actor Song Joong Ki and Lee Kwang Soo are considered two close friends in Korean showbiz. At this time, both of them returned to the screen, some acted in TV series, some participated in Vietnam - Korea cooperation films.
Actor Song Joong Ki, who is married to Katy Louise Saunders, returned to the screen with the film "My Youth", a romantic, emotional work. The film premiered on JTBC (Korea) from September 5.
On September 4, at the press conference to launch the film, Song Joong Ki shared: "It's been a long time since I've acted in a romantic film, I really felt moved".
The actor confessed: When I look back at the characters I have played, most of them are images of superheroes, Wolves... rarely characters attached to reality. Therefore, taking on an everyday role in this work makes me very happy.
On the same day, Lee Kwang Soo had a new film release. The actors came to Ho Chi Minh City at the event to promote the Vietnamese-Korean collaboration film "Tay Anh Ket Mot Sao".

Lee Kwang Soo plays a top Korean star, suddenly "stuck" in Vietnam during a tour, unexpectedly receiving a "lightning of love" with a simple cleaning female employee (played by Hoang Ha).
Song Joong Ki and Lee Kwang Soo have been close since appearing together on the show "Running Man" in 2010. The "rookie" couple of the same age (1985) gradually became close and attached like brothers.
Song Joong Ki once shared that Kwang Soo was the only artist friend he took home to play with before joining the army. He also enthusiastically helped his best friend's sister organize the wedding.
That friendship not only exists behind the scenes of the show, but also spreads on screen. They worked together in the movie Ni Nice Guy.
Behind the scenes of "The Sun's Returns", Song Joong Ki caused a stir when he wrote the words "Joong Ki and Kwang Soo" on a small rock on Navagio beach, Greece. Kwang Soo also appeared as a guest in this film.
The wedding location at Song Joong Ki and Song Hye Kyo's wedding was also taken by Kwang Soo.
In recent years, there have been some signs that have made fans question the change in the relationship between the two artists.
According to Soompi, in July 2023, Song Joong Ki was absent from a trip to Japan by a group of friends including Lee Kwang Soo, Kim Woo Bin, Jo In Sung, D.O. (EXO), Kim Ki Bang and businessman Lee Ki Hoon.
When Song Joong Ki returned to the screen through "The Youngest Son of a Tycoon", the audience did not see the shadow of Kwang Soo with Jo In Sung, Yoo Ah In... encouraged on social networks as before.
Not only Kwang Soo, Song Joong Ki is also said to be far from many friends after remarrying his British girlfriend. MC Yoo Jae Suk once admitted that in a TV show, he felt uncomfortable when interacting with Song Joong Ki.
The last time the two best friends appeared together was at a mutual friend's wedding in April 2021.
