What is the feeling of heartbeat?

The feeling of "heartbeat" varies from person to person. It is not only a person's psychological reflection, but also a person's direct sensory response. This is the basis of the feeling of love. I will easily and quickly detect this reaction, and generally this feeling will be stronger when it happens to someone for the first time. If I have the same strong feeling several times in the future, it will evolve into a feeling of "love". If the "heartbeat" of the same person decreases with the increase of meeting times, it is only the real "heartbeat" rather than "love". In addition, the feeling of "love" is that you will inadvertently show it to someone in psychology and behavior, and it will grow slowly in your heart, and sometimes it is not easy for you to find it yourself.
