If I quit my contract can I still get severance and transfer my housing

For context I plan to obtain my f2-7 visa soon and my contract is 1.5 years. However by August it will have been one year and I wish to quit. There’s many reasons for this. But I’m curious could they take away my severance? Also my name is not on any housing but I would just like to transfer it over. However if I decided to just leave Korea they couldn’t take it out of my severance right?
