사과 (Apology) is a social and emotional expression of regret or remorse for an action that has caused harm or offense to another person. It often involves acknowledging the mistake, taking responsibility, and expressing a desire to make amends. Apologies can help repair relationships and restore trust between individuals. In many cultures, a sincere 사과 is considered an important aspect of interpersonal communication. It can be verbal or non-verbal and may include gestures such as bowing in Korean culture or offering a gift as a sign of goodwill. A well-delivered apology can lead to healing and reconciliation.
