Bangkok Traffic (Love) Story

Thirty-year-old Mei Li (Cris Horwang) has never had a boyfriend. She gets drunk on her best friend Ped's (Panisara Pimpru) wedding night, upset that she is the only single girl left in her friend group. Driving home intoxicated, she crashes her car but is aided by an attractive man. When she reaches home, her family scolds her and bans her from driving, forcing her to commute by public transport.

The next night, Li accidentally catches their teenage maid having sex with her boyfriend on their rooftop. Li's father demands to see the boy's guardian, who turns out to be the man who helped Li the previous night. The man, Loong (Theeradej Wongpuapan), is a tenant at the guest house the boy caretakes. On another night, Li encounters Loong on the BTS Skytrain, where she accidentally breaks his sunglasses. She buys Loong a new pair of sunglasses and writes her phone number on the box, hoping he would call her. After waiting in vain, Li and her neighbor Plern (Ungsumalynn Sirapatsakmetha) meet Loong at the video rental shop he frequents, and the flirtatious Plern cleverly obtains Loong's phone number and learns that he is a night shift engineer for the BTS Skytrain. However, Plern refuses to give Loong's number to Li, and instead becomes a cashier at the video rental store. In retaliation, Li summons Plern's three boyfriends to the store, causing a ruckus that Loong gets caught in resulting in the smashing of 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.

Li meets Loong again on a skytrain, and tells him that the pictures might have been published because of her, but Loong doesn't mind. Loong tells her that Kob is his ex-girlfriend, and they broke up because their time schedules didn't match. When the skytrain arrives at Ekkamai Station, Li suggests that they watch the stars at the Bangkok Planetarium and see an exhibition about a comet that will be appearing soon. Li asks Loong to watch the comet with her in Bangkok. Later, before the Songkran holidays, Loong asks Li to come celebrate by throwing water.

During the Songkran festival, Plern joins them. Li doesn't enjoy the festivities because of her. Li knows Loong's address, which is a guesthouse next to Chao Phraya River. Li changes her clothes and goes to see Loong, and finds him asleep. Li falls asleep next to him. After she wakes up, Loong asks her to travel around Bangkok. Loong asks Li to come to family day at the BTS, as he can take her into the depot. Loong takes pictures, but Li damages the camera.

On the family day visit, Li finds out that Loong is leaving in two days time to spend two years studying in Germany. They say goodbye on the Taksin Bridge. Loong sends Li a box when he arrives in Germany. Inside is the mirror from her car from when they first met, the damaged sunglasses, the broken laptop, Bangkok Planetarium tickets, and the damaged camera, with the memory card still inside. Li looks at the pictures. She rushes to Suvarnabhumi Airport to try to stop Loong, but she is too late. On that day, the comet orbits to the earth. Loong watches the comet from on board his plane, while Li watches it as well.

Two years later, while going to work one evening, Li accidentally meets Loong on a BTS Skytrain. Loong works a day shift and has been back in Thailand for a few months. Both get off the Skytrain at Siam Station, which is the interchange station between the Sukhumvit Line and the Silom Line. Li goes downstairs to change to a different line and doesn't turn back to look at Loong. Li gets on her train, but the electricity goes out. Passengers call their friends or family to say the train has stopped. Li's phone rings; it is Loong. He asks Li to again celebrate Songkran. Li replies that she is free for the holidays. When electricity comes back on, Loong is on the same Skytrain, standing next to Li. He tells Li that she has his number now, and to save it.

Bangkok Traffic (Love) Story was sponsored by the BTS, and the movie includes many scenes depicting maintenance work on the system and its infrastructure. The film was promoted as part of BTS's tenth anniversary celebrations. The film's Thai name, Rod fai fah.. Ma Ha Na Ther, translates as "Skytrain, coming to meet you", and is a word play on Rot Fai Fa Maha Nakhon (รถไฟฟ้ามหานคร), which is the Thai name of the MRT underground system. The English title is abbreviated BTS to coincide with that of the skytrain system.[3]
