... The so-called love at first sight, in a large sense, is caused by the serious differences between the two.
There is a huge difference between the other person and the person he usually interacts with. This difference caused surprise at the first moment. Note, surprise rather than shock, after all, it is still within the scope of aesthetics... This resulted in various physiological reactions such as accelerated heartbeat and inability to look away. It was these reactions that were misjudged as falling in love and then gave rise to the saying of love at first sight.
In short, love at first sight is the product of the shock of difference.
