意味

Stating that an action is not obligatory.

🌍

文化的背景

In Korea, refusing an offer once or twice is common to avoid appearing greedy. Using '~하지 않아도 돼요' helps the other person feel comfortable in their refusal. In Korean companies, a superior might use this phrase to show they are 'approachable' and not overly demanding, which is a modern leadership trend. When receiving a gift, it is culturally expected to say 'You shouldn't have' using this phrase. It shows you value the person more than the material item. On platforms like Instagram, this phrase is often used in 'healing' posts, telling followers they don't have to be perfect.
