Koreans don't like to say “no” directly because they don't want to hurt the other person's feelings. They might give out some non-verbal cues to convey their refusal or disagreement. To avoid confrontation or rudeness, Korean conversations, as you might have seen in many K-dramas, are full of “Maybe...”, “I think it's possible that…” However, some foreigners who are accustomed to hearing a “no” that means “no” might be confused. They will likely want to hear clear, direct and factual statements.
