Adora Anae wants to leave Korea because of corona. It is stated in the standard contract that contract could be delayed maximum 14 days due to the inevitable outside force. However she asked to the team that she wants to get out of Korea whatever the contract says.
She even wrote an official document to FIVB arguing that Korea should finish the league, not delaying. She also requested to compensate players with money.
IBK is trying to stop her because other foreign players could be influenced if Anae is leaving.
