1. Emotional expression: Boys convey love and intimacy to girls by holding hands, which is a form of body language that can deepen the emotional connection between the two.
2. Manifestation of protective desire: When holding hands, the boy is usually on the outer side, which to some extent demonstrates his protective desire for the girl, hoping to ensure her safety and bring her a sense of security.
3. Enhance intimacy: Holding hands while walking can naturally bring two people closer physically, promote physical contact, and deepen the sense of intimacy and trust between each other.
