"Dual-faced" refers to having two different personalities. Just as each individual faces different situations and encounters various challenges in their lives, having two faces represents the reality that we face different personalities in different situations.
Each of our personalities has different qualities, traits, and habits that make us appear dual-faced. Sometimes we are happy and cheerful, while at other times we are sad and depressed. Sometimes we are successful and energetic, while at other times we are unsuccessful and frustrated.
