If you don't know the cause of your love, you need to look at the person. Not everyone has piercing eyes and can find that person immediately in the vast sea of people, so you can't give up; you can't compromise; you can't give in. We can't choose birth; we can't choose appearance; we can't choose gender, but we can decide ourselves, just like fairness; just like human heart; there is never a standard of measurement, we can only have a clear conscience.
