It would be safe to assume to @BestBoy

The real question: Is her dad married to her mom?

lmfao

well that's a way to sail the ship

Wow, they had the same reaction as I had. When has he come back? Didn't the dad want to do something with his children?
I somehow doubt we get to see him any time soon

Hyejin's husband has finally appeared... Well, not really, but Soojin has finally acknowledged that she has a dad, and that he and her mom are spending time together. I get the feeling that he'll just be a phantom character and that we're never actually going to see him.
