1. Lee Kwang Soo

This amazing friendship started back when Song Joong Ki and Kwang Soo starred together on Running Man, and their bromance continues to this day. Song Joong Ki even used one of his leave days from the military in order to attend Kwang Soo's sister's wedding!

Kwang Soo also recently made a cameo appearance to support Song Joong Ki in Descendants of the Sun.


Even more adorable, Song Joong Ki paid tribute to their close friendship by writing a message to Kwang Soo while he was filming in Greece. His message reads "Joong Ki ♥ Kwang Soo (Asia Prince)."

It's impossible not to love these two!

2. Jo In Sung

Jo In Sung and Song Joong Ki began their friendship on the set of the movie A Frozen Flower in 2008 and have remained best buds ever since.

Even better, Jo In Sung is also close friends with Lee Kwang Soo! The three often go on vacation together, most recently taking a trip to Thailand last summer to celebrate Song Joong Ki's release from the army.

3. Kim Jong Kook

This is another great friendship that started during Song Joong Ki's Running Man years. Just recently, Song Joong Ki thanked Kim Jong Kook for helping him get in shape for Descendants of the Sun. I can't think of a better person to get training tips from!

In addition, Song Joong Ki says that he has remained good friends with the entire Running Man cast. Hopefully that means we can see him on the show again soon as a guest! Everyone was so excited when both Song Joong Ki and Jo In Sung came on the show last June!

4. Park Bo Gum

Both Park Bo Gum and Song Joong Ki are represented by the same agency, Blossom Entertainment, which gave them a chance to form a close friendship. They both have stated in interviews that they enjoy monitoring each other's projects and often give feedback to each other. 

If you haven't noticed already, Song Joong Ki's friendships often overlap! Recently, both Park Bo Gum and Lee Kwang Soo made an appearance at Song Joong Ki's fan meeting in Seoul to help support their friend. Too cute!

5. Jang Geun Suk

Jang Geun Suk posted these photos back in 2011, showing off his friendship with Song Joong Ki. Jang Geun Suk asked fans not to misunderstand!

6. Jang Hyuk

Song Joong Ki and Jang Hyuk both acted in Tree With Deep Roots, where Song Joong Ki played the younger version of King Sejong. They previously were represented by the same agency and reportedly developed a close and supportive friendship during that time.

Here's a cute conversation between the two that was posted online!

Their conversation refers to the drama that they filmed together. It reads:

Song Joong Ki: “Hyung-nim ~ I really enjoyed watching the last episode. It was the best.”

Jang Hyuk: “It is all thanks to your great efforts in the beginning ^^. Let us meet up soon.” 

7. Park Yoo Chun

Yoochun and Song Joong Ki became friends while acting together in Sungkyunkwan Scandal. You can see their friendship in action in the adorable video below!

Yoochun also introduced Song Joong Ki to his JYJ bandmates Jaejoong and Junsu, and they both have also maintained a close friendship with Song Joong Ki. Junsu even recently sang the song "How Can I Love You" for the Descendants of the Sun OST.

8. Im Ju Hwan

Im Ju Hwan and Song Joong Ki started their friendship after starring together in the movie A Frozen Flower alongside Jo In Sung. Song Joong Ki was even there to send Im Ju Hwan off to the army!

9. Yoo Ah In

Song Joong Ki and Yoo Ah In won the Best Couple Award at the 2010 KBS Drama Awards for their fantastic bromance in Sungkyunkwan Scandal. What's even better is that their onscreen bromance developed into a real-life friendship!

Can we get a Sungkyunkwan Scandal reunion soon?!

10. Song Hye Kyo

Following their recent success on Descendants of the Sun, it looks like these two are closer than ever. While they have denied any dating rumors that have sprung up, they will continue to support each other in their future projects as both friends and colleagues.
