The relationship status between Single’s Inferno 5 stars Kim Go-eun and Jo igeon has finally been revealed and it’s more complicated than a simple yes or no.
While the two confirmed they are not officially dating, they also made it clear their connection hasn’t ended. In fact, they described their relationship as “moving forward,” sparking renewed interest among fans.

On March 26, Kim Go-eun and Jo igeon appeared together on the YouTube channel “When You Open Your Mouth” (입만열면), where they participated in an interview while hooked up to a lie detector.
From the moment they appeared, their natural chemistry and comfortable physical closeness raised questions about whether they were already a real-life couple.
When asked directly,
“Are you dating Kim Go-eun?”
Jo igeon answered:
“No.”
The lie detector confirmed his answer as true, officially ruling out that they are currently a couple.

Despite not being in a relationship, Jo igeon revealed that things between them are far from over.
He explained that during the reunion filming, the two cleared up misunderstandings and expressed their feelings for each other. They even went on dates and stayed in touch afterward.
However, another misunderstanding caused some distance again.
After watching the show and reflecting on their actions, they were able to resolve things once more.
“We met again, talked things through, and now we’re getting along well,” he said.
“It’s hard to say we’re dating, but we’re still in contact.”

When the host asked,
“So your relationship is moving forward, right?”
Jo igeon turned to Kim Go-eun and asked her directly.
Instead of answering, she simply smiled, leaving the moment open to interpretation.
Later, when asked if the relationship is developing,
Jo geon said, “Yes,”
and the lie detector confirmed it as true.
Kim Go-eun also shared:
“We’re in the process of getting to know each other again.”

Jo igeon also showed a positive stance toward public dating.
“If the other person wants it, I’m willing to go public,” he said and once again, the lie detector confirmed he was telling the truth.
The host summarized their situation perfectly:
“It feels like you’re at the stage where friendship is slowly disappearing and turning into something more.”
In the video’s final “cookie scene,” the tension didn’t stop.
Jo igeon jokingly asked Kim Go-eun:
“Would you go on ‘EXchange’ (Transit Love) together?”
She replied:
“You have to break up first to go on that.”
The unexpected answer shocked everyone and added even more mystery to their relationship.
At this point, Kim Go-eun and Jo igeon are:
They are somewhere in between not quite a couple, but clearly more than just friends.
And that’s exactly why fans are watching closely.
Will they eventually confirm their relationship?
Or remain in this “almost” stage?
For now, one thing is certain:
their story didn’t end with Single’s Inferno 5.
