Why are slow-heating people easy to be single?

Because slow-paced people need some time to get familiar with each other, and then they will let go of themselves when they are familiar. Personally, I think he is very passive. If a person likes a slow-moving person and others spend too much time on the slow-moving person, he will never get a response from the slow-moving person. In the long run, he will be impatient or think that people who are slow to heat don't like themselves and give up because of wishful thinking. Even if a slow-moving person has someone he likes, it is difficult to take the initiative.
