A passage from a professor in Peking University:

There is a magnetic field between people.

Some people can't get close to each other no matter how long they know each other, but they will become good friends at first sight, so making friends and falling in love are sometimes the same, depending on fate.

We became friends not because of fate, but because we were supposed to be friends, so this can be regarded as fate, or worse, a miracle that we met and were attracted by this vast planet.
