It looks like Lee Kwang Soo is feeling betrayed by his bromance partner Song Joong Ki.
Following the Song Song couple's marriage news, Lee Kwang Soo expressed frustration via Instagram.
The model-actor shared a photo of the bromantic note Song Joong Ki left at the sets of 'Descendants of the Sun' and asked, "So then what was all this?"
Sorry, Kwang Soo. Song Joong Ki's real romance was with Song Hye Kyo after all.
