Generally speaking, girls like to slow down, and they don't feel cheated after a long time; Boys like to be in a hurry and feel that they are taking advantage, but the idea of taking advantage at a loss is unhealthy. To start from your own heart, "like someone, or even lose yourself", the relationship between suffering and loss will not last long.
If the relationship starts quickly, you may both be attracted to each other's characteristics or clothes at some moment. Of course, you may also be infatuated with each other's face value and temperament, thus showing your love and admiration in a hurry.
After the passionate love period, there is no "beauty filter" and no hormonal blessing. When many details of life conflict with the three views, it is likely that some contradictions and a series of problems will follow, and the relationship that cannot stand the test may "go their separate ways" and become strangers.
