The outline of those things that fell in love at first sight.

Based on the modern city, this film intercepts a large number of poetic fragments in life, and tells the love story of six young people who fell in love at first sight because of an unexpected encounter through multi-viewpoint narration.

Xiao Tao (played by Xu Tao) is a courier. Xiao Tao is no stranger to this city that runs around the clock, but it will take him some time to get used to the speed brought by motorcycles replacing electric bicycles. Xiao Tao likes to watch others' faces when receiving express delivery. Some of those expressions are excited, some are nervous and some are unconvinced, but Xiao Tao thinks those expressions are true, because for the courier, he is just a courier, and people don't need to hide anything from him.

Toby Lin (played by Xie Xinyi) is a girl Xiao Tao met by chance when delivering the express. From the moment they landed, a love story was doomed between Xiao Tao and Lin Xi. In order to see Toby Lin who waved away after being knocked down again, Xiao Tao accepted a courier from other workers in order to increase the chance of bumping into Toby Lin again. After many troubles, Xiao Tao not only ran into Toby Lin again, but also had the honor to walk into Toby Lin's home.

Toby Lin is a writer of love novels. However, since my best friend Chen (played) inexplicably left her boyfriend Hao Tian (played by Chang Wei) and fell into the haze of lovelorn, she also "infected" the feeling of no love and opened an online shop at home. Toby Lin was so absorbed in her online shop that she didn't realize her chaotic life and began to change quietly. It was not until Chen Lai took care of the accidental fracture that she discovered that someone had a crush on her, and there were eggs, laver, dried shrimps and so on in the Lins' refrigerator.

(Li Unique) is the business backbone of a real estate company. The encounter with "literary master" Zhang Jialiang (played by Harrison Lee) originated from a game in Zhang Jialiang. The game has started. Zhang Jialiang found a sense of security around Rulu, who was several years older than him. Rulu knew the game was a trap, but he just didn't want to escape. On the contrary, he fell deeper and deeper into the romance and excitement created by Zhang Jialiang.

Rulu disappeared from Zhang Jialiang's sight; Toby Lin mistook the thief who broke into her house for someone who had a crush on her. But the thief came to the Lins' house not to steal, but to pay back the money. It turns out that the thief Wang Wei (played) stole Chen's wallet on the road. Just as he pretended to fall to get it, he thought he was really going to fall and gave him a hand. This little gesture and that look back had a chemical reaction in Wang Wei's heart. In addition to 74 1.5 yuan cash, there is also a business card with the name "Toby Lin" printed on it. Wang Wei mistakenly thought that Toby Lin was the owner of the wallet and 74 1.5 yuan cash.

Wang Wei doesn't want to be a thief anymore. However, when Wang Wei appeared in front of Chen with a brand-new image, a disaster came quietly, and Wang Wei, who had washed his hands, was blackmailed by the fifth uncle behind the scenes. Wang Wei miraculously survived. Perhaps it was Chen, the man he thought was called, who kept him alive. Rulu resigned, Zhang Jialiang went abroad in frustration, and Toby Lin found the final love answer from "I can send express mail to everyone, but I don't know how to send myself to your heart".
