According to several sources, ex-idol-turned-actress Nana is in a long-term relationship with her music video co-star Chae Jong Seok.

On December 5, the news broke, and now fans and netizens are going crazy connecting the dots shared by the couple on social media.

Even though neither star's agency has weighed in on the rumors, fans did a bit of sleuthing on the pair's Instagram accounts and found a cluster of "Lovestagrams" that suggest the two are indeed dating.

The word references couples sharing matching snapshots on social media, usually of the same pose in the same location but without being in the frame together.

Photos uploaded by Nana and Chae had started to go viral on the Korean online community Instiz, showing them with matching backgrounds and timestamps, most notably during a trip to Bali.

It comes as one user commented in disbelief, writing, "I can't believe no one noticed before."

Fans are shocked to learn about their relationship.

Others noted that they were amusingly casual in describing their experiences with absolutely no mention of the romantic subtext. Another netizen commented, "They did it so blatantly, LOL."

While Nana and Chae Jong Seok have yet to issue any follow-up confirmations or comments about their alleged relationship status, fans are very much looking forward to seeing how the story develops.

In the meantime, while fans and followers alike are drawn to the couple's seemingly romantic tale, the pair have reminded the world through these early days at least that (often) love is right in front of your nose.
