It's probably because they used ai for translation and didn't double check the pronouns. Since Korean rarely uses pronouns, ai hallucinates the pronouns to make sense in English. Consistently wrong pronouns is how I've been able to tell when the translators use ai and are too lazy to double check the translation

I just re read de side.02 and realice that the translation is wrong. It takes Chowon and Heesung as women. It uses the possesive pronoun "her" as when it says Her ex husband and for heesung it says Aunt
