1. Hidden true self: These individuals may choose not to easily reveal their true thoughts and feelings for self-protection or conflict avoidance, making it difficult to establish deep emotional connections with others.
2. Social strategy: They are good at using social skills, appearing friendly and enthusiastic on the surface, but may only be polite or maintain personal image, without truly investing emotions to understand and care for others.
3. Lack of trust: Past experiences or personality traits may make them cautious about building deep interpersonal relationships, making it difficult for them to easily trust others. Therefore, even if the relationship appears good on the surface, they still maintain a certain distance in their hearts.
