Fans of Netflix’s hit dating show Single’s Inferno 5 are convinced that one final couple may have taken their on-screen romance into real life.
Following the finale, viewers began piecing together clues suggesting that Hee Sun and Su Been could still be dating after the show. The speculation started when Su Been’s friend uploaded an Instagram story showing the Single’s Inferno 5 finale playing on a TV. Hee Sun was also present at the watch gathering, leading many to believe the couple watched the final episode together.

Adding fuel to the rumors, fans noticed that in photos Hee Sun posted in 2025 — long after filming for the show had wrapped, she appeared to be wearing a cap and hoodie that closely resemble items Su Been was seen wearing on Single’s Inferno 5.

Online communities quickly circulated side-by-side comparisons, with many claiming the items looked identical.

Some claimed that they were common items which can easily be bought.

While neither Hee Sun nor Su Been has addressed the rumors, fans believe the clues are too specific to ignore. From watching the finale together to allegedly sharing clothing, many are convinced the couple quietly continued their relationship off-camera.
