is the fl related to anyone in her adoptive family? no.
i do understand how it's weird because obviously she's adopted but i need ppl to stop misusing the word just because the dynamic is not normal/strange. i also need translators to stop pushing their weird fantasies in manhwa translations because she is clearly saying oppa, not addressing him as big brother but as a respectful term to someone older.
either way, i do not like this story because it lacked depth, which is funny considering there's lots of dialogue. i'm also not a fan of the pacing and i do believe this story's potential could have been executed much better. i made it to chapter 71 and im honestly annoyed with the pacing, especially because the plot is so good i just wish it was better than this. im dropping for now.
