When Lin Xiaotang woke up, the spicy taste of last night's hot pot was still in her mouth. She turned over and touched the mobile phone on the bedside table. The screen was dazzlingly bright. It's 7:43 in the morning and the alarm clock hasn't gone off yet. She habitually opened WeChat, and the first post in her circle of friends was a nine-square grid posted by her best friend Zhou Yufa. It was located at the Liberation Monument in Chongqing, with the text "Hotpot", and she went to eat again. Lin Xiaotang muttered, and when he was about to click like, his fingers suddenly stopped. She clearly remembered that Zhou Yu was still working overtime yesterday, saying that he couldn't finish the project and didn't even eat dinner. Lin Xiaotang sat up and rubbed his temples. Something was jumping in my head, like some memory fragments were popping out. She closed her eyes and tried to grasp those pictures: the bottom of the red oil pot in the hot pot restaurant, Zhou Yu's expression that was so spicy that he was breathing heavily, and the man sitting next to her. Man? Lin Xiaotang opened his eyes suddenly. She didn't recognize the man, but in her memory, he was sitting next to Zhou Yu, wearing a dark blue shirt, with the cuffs rolled up to his forearms, and an old-fashioned mechanical watch on his wrist. She had never seen that watch. Xiaotang! Have you gotten up yet? Mom's voice came from outside the door. If I don't get up, the buns will get cold!
