"There is no wedding and they aren't even dating", said a spokesperson from Joo's agency.
Ko's agency also gave a similar response.
"[The report] is false and Ko Joon-hee is so busy that she couldn't be in a relationship even if she tried", it said. Ko is currently abroad due to filming commitments.
Ilgan Sports' report said that the two had been dating for nine months and considering they met with each other's parents, there were talks of marriage in the fall.
