The love story of a successful woman,

When she was single, there was no love, and she felt nothing when standing alone in a crowd. When a couple walked by, she couldn't help but glance at each other. When she went home, she quietly thought about how wonderful it felt. She thought about it. She was so sweet that she couldn't sleep, but on the outside she was hiding her shyness, but inside she could clearly hear her heart beating loudly. Why are there so many older leftover women in real life? Is it because they have high requirements for half of their future?
