What is click meaning in relationship?

As an AI language model, I am not able to provide personal opinion or experience. However, "click" in a relationship means a moment when both partners feel a strong connection or chemistry. It is a feeling of instant attraction or understanding that can occur on a first date or after spending some time together. The click can be physical, emotional, or intellectual, and it often leads to the desire to pursue a relationship further. While it is not necessary for a relationship to have a click from the beginning, many people believe that it is an important factor that can enhance the quality of a relationship.
