I'm pretty sure it's because of its original language.
I don't know Korean but it has a similar grammatical structure to Japanese. Once you know who the subject of the conversation is, you can drop the subject from the sentence all together and if you are mentioning someone by name, you don't have to reference gender.
Or if it follows Chinese, they don't have a gendered pronoun; he, she, and it are all the same word.
He is a SHE???
