Because I am so confused on whether she became genderless upon returning to her birth world.. I thought I saw boobs. But since Hae In identifies as female, daughter it is!
In the other world she is female. When she comes back to her birth world she becomes genderless but her father calls her a son, she still refers to herself as female. Everyone else thinks of her as male in her birth world I think the translator made a mistake when translating thought bubbles and speech bubbles when people call her with female prounouns.
Okay so they might be all a bunch of what now?
