Gong Hyo Jin and Ryu Seung Bum worked together in 'Splendid Days' in 2001 and became a real-life couple following the end of the drama. The two became one of the most fashionable and also one of the longest-lasting celebrity couples.

However, they officially confirmed their breakup in 2012 after 10 years together. 

Actor Ryu Seung Bum has been taking a break from acting to study fashion overseas. After a long time away from the public eye, Ryu Seung Bum was recently spotted on model Bae Jung Nam's Instagram in a friendly snapshot. 

Seeing this, Gong Hyo Jin commented, "Aigoo, our fashionista Seung Bum ee is back, again?" Bae Jung Nam replied, "Keke he's back, he's back!!"

Netizens reacted to their unchanging friendship with comments, "How cool", "I wonder if they could really be that cool about one another. In a way, I feel like they will end up getting back together and get married. They both are cool."
