On October 17 episode of SBS' television show 'Running Man', the members played 'Octopus Game' together.
Before the game began, they took some time charging their energy by themselves.

While he was taking selfies, Song Ji-hyo came behind him and posed so that she could be in the photos as well.
They looked like a couple taking photos with each other while on a date.

Then, they commented, "Are you two taking photos to upload on your Instagram as part of 'lovestagram'?"

But Song Ji-hyo followed the direction of his hand; she playfully tried not to miss the opportunity to take photos with him, making Yu Jae Seok and Yang Se Chan smile.
