The answer seems to be... probably?
As Lee Joon's discharge news has come out (and that Lee Joon would be taking the baton from Jung So Min as the 'Young Street' DJ), both Lee Joon and Jung So Min's labels were reached out to on their relationship status. Lee Joon's label PrainTPC answered, "They're doing fine", but Jung So Min's Blossom Entertainment said, "We can't confirm the actress' private information."
What do you make of the two labels' statements?
Ummm it's not our business...
