what are you confused about? maybe i can try to help lol
What did the last line meant
ooh okay so when she said that, she was talking about the unnie part, she was saying how she never calls anyone unnie in front of her
Too add to the other person, unnie is like a formality, meaning a sister or someone close to you, its like sunbae. The friend was saying how she's never used formalities like that on another woman, especially on one that she claims to "not like"
i'm confused rn
