"Men and women are like the two poles of a magnet. Most opposite sexes attract each other, but some of the same polarity fall in love. They need to overcome a lot of resistance before they can embrace each other." There is a saying circulating on the Internet.
But when Yu Shu was in the third grade of junior high school, what his physics teacher told him was: "Magnets of opposite sexes attract each other and same sexes repel, just like boys and boys will not be together."
At that time, Yu Shu didn't understand why the girls questioned that sentence, but maybe, he understands now.
Motto: Even if you don't love yourself, there are still people in the world who love you
