Feelings are different from dividing spoils, it's never possible to be fifty-fifty. After falling in love with someone, you will find that the proportion of emotions is always 4:6, 3:7, 2:8, 1:9. The more you give, the less you get in return. Or sometimes, you get everything without giving anything, and hold all the winning cards. This is the illogical logic of love. Therefore, the ones we fall in love with are always the ones we shouldn't.
