Fans are growing curious because of a surprise Instagram screen shot that is going around social media, that seems to say that Joy and Seulong might have filmed a music video together.

A videographer named Minkyu Jin shared a photo on his Instagram with a caption that reads, "Friend, you should have a proper stand-in..." The photograph depicts a man who seems to be a production staff member sitting at a table. It was the hashtags that made people curious as he included, "#friend #standin #joy #imseulong #mvfilming #filmingset," making the fans suspect that the two idols are working on a project together.

Some speculate that this collab could be for SM Station, which has SM artists collaborate with other label's musicians. While others suspect that Joy is starring in Seulong's new music release.

I guess we will found out eventually! Can't wait to know exactly what the two are working on!
