On Ped's (Panisara Pimpru) wedding night, her close friend, Mei li or Li (Cris Horwang), had drunk too much wine and had fallen asleep in Ped's hotel room. Li woke up in the early hours, she drove back to her home however she had a car accident on her way and this was where she met Loong (Theeradej Wongpuapan). When Li arrives home, her family scolds her, and her father forbids her to drive, so Li has to go to work by public transport.

One night, Li wakes up in the middle of night and goes to the roof of her house. She accidentally catches her maid and her boyfriend, who are also on the roof. Her maid's boyfriend calls his 'elder' (responsible adult), who turns out to be Loong. Li next meets Loong again at a BTS Skytrain station. This time Li accidentally breaks Loong's sunglasses. Li buys a replacement pair of sunglasses and writes her number on the box. She arranges to 'bump into' Loong to give him the new sunglasses. After waiting for Loong to call, Li goes to a video rental shop that Loong visits regularly. Li's neighbor, Plern, uses a trick to get Loong's mobile number, but later goes to work at the same video store instead of giving Loong's number to Li. As revenge, Li uses Plern's mobile to send messages to Plern's three boyfriends, inviting them all to the store at the same time. Loong comes into the shop, and accidentally drops his laptop.

Feeling responsible, Li take Loong's laptop to Ped's husband, but he can't fix it. Li goes to return it at the BTS office. When Loong finishes work, he finds Li, and they ride the BTS to get home. Loong decides to throw away the laptop and its bag. Li picks the bag up out of the garbage bin and takes it home. There are many things inside, including film negatives. Li has the film printed, and finds there are pictures of Loong with Kob Kavita (Taksaorn Paksukjareon), an actress in "Saint's Tear", a popular television series. The photo printing shop owner posts the pictures on the internet, as they are of a famous actress.
