What does 당신 mean?
당신 (dangsin) means: you (spouses, writing, arguments).
The textbook trap. Dictionaries do list it as a slightly respectful 'you', but face to face it survives in three places: husband and wife addressing each other, ads, lyrics and written text speaking to an unnamed reader, and fights — the NIKL dictionaries record a separate disparaging sense used when confronting someone. Say 당신 to a stranger or an older person and it can sound like you are picking a fight.
