Song Hye Kyo and Hyun Bin are rumored to be dating.

Netizens went berserk after South Korean actress Park Sol Mi uploaded a screenshot of The World To Live In soundtrack. Things escalated quickly after Hye Kyo commented on the said post. "Sister… Hahaha," the Descendants of the Sun actress wrote.

Interestingly, Sol Mi disabled the comment section soon after avid supporters of Song Hye Kyo started asking if she and Hyun Bin are back together.

Most, if not all, fans of Hye Kyo have can vividly recall when Hye Kyo posted a photo of her donning a necklace with letters "S" and "H." While some think that the letters were the Encounter star's initials, speculations have it that it could mean Song Hye Kyo and Hyun Bin.

The former wife of Song Joong Ki, also, shared a snap on Instagram that looked very similar to the Crash Landing On You actor's commercial shoot location.

Both Hye Kyo and Hyun Bin have yet to address these dating speculations. So, devoted supporters of the two Asian superstars should take these rumors with a grain of salt until everything is proven true and correct.

To recall, Song Hye Kyo and Hyun Bin were first linked to each other in 2018 after working together in The World They Live In series. Initially, the two Hallyu stars denied their romance. It was only after a year when Hye Kyo and Hyun Bin confirmed that they were an item.

The former lovebirds broke up in 2011, just a few weeks before Hyun Bin started his mandatory military service. Neither Song Hye Kyo nor the Secret Garden actor revealed the cause of the split.

However, representatives of both parties claimed they decided to end their relationship because of their hectic schedules and the "overwhelming" stress they experienced because of the significant amount of attention they were getting at the time.

In Oct. 21, 2017, Song Hye Kyo tied the knot with Song Joong Ki in a heavily-guarded ceremony in Shilla Hotel in Seoul City, South Korea. However, the two stars announced their divorce on June 27, 2019.
