Saburou is in his 20’s and works at a perfume company, living a normal life (without a girlfriend though). One day, he heads out with one of the part-time girls, Misa, since it was her birthday and he bought her a present. The next day, girls kept coming on to him… something must have happened to make him so suddenly popular. With some research, he found out that it must be because of some type of pheromone. Was it because of something he drank or maybe the flowers he bought for Misa?
