The first chapter describes him as a korean-American lawyer, but I’m guessing your right about the mistranslation Kara (♡ˊ꒳ˋ)
I didn't reread, but they probably said he's Korean-American, not cause he's half American, but probably cause he lives in America and has American citizenship.
At the start it says Leewon is Korean-American but I thought that his dad was Russian? Someone explain pls I’m confused
