It turns out that love is chemistry. Moreover, it is complex, multicomponent, and sometimes unpredictable.
When two people in love meet, there is tension between them, some kind of awkwardness. They don't understand what's going on, it used to be called love at first sight. In fact, it creates a special energy that penetrates from one to the other and mixes like air from different rooms.
Chemistry in a relationship can develop in different ways, depending on personal priorities, values, and life experiences. Relationships can reach a new level, for example, with a wedding!
