On a stormy night, college student Ling (Takuto Hamaya) was stuck in the middle of the road due to a car breakdown. A young man on a motorcycle appeared in front of Ling, who was at a loss. He repaired the car skillfully and left without saying his name. Ling's mind was always lingering about him who had helped her. Her friend Kai (Reio Nagatsuma) from the same department told Ling what happened that night, and Ling was full of longing for him. At this time, Ling heard the story of the "legendary senior" circulating in the architecture department where the two studied. Then she found out that the senior was Arashi (Shoma Nanyun) who saved her that day. The two reunited at a party with their seniors in the department, but Arashi said that Ling "didn't remember" and Ling was disappointed. But on the way home that day, Ling, who was unable to move again due to a car breakdown, was helped by Arashi to go to his house again. There, Arashi asked for her body in the name of repair money, and Ling couldn't resist Arashi's sexiness and almost accepted it. Ling finally regained her rationality, avoided Arashi, and got through that occasion. But then, Lanshi appeared in front of Ling and demanded the price for the repairs. Even if she tried to avoid him, Ling, who was still anxious, took Kai to the venue of the illegal motorcycle race where Lanshi participated in order to take revenge. However, it was Lanshi who rescued Ling from the crisis in the heavily guarded venue. And Kai, a friend who was involved in the commotion, also had the worst encounter with Fuma (played by Suzuki Akira) there...
