I am a rational person. I don't believe in love at first sight. At least I don't believe that I will fall in love with someone at first sight. I believe that love will develop over time. Only after getting along with each other will I be assured of a person's character and then fall in love with him. But I forgot to calculate how long it takes to fall in love, so when I knew that I had already fallen in love with him unknowingly, we had already passed each other.
