Yoshio Yoshida knows better than anyone that appearance is everything. Because of his almond-shaped eyes, short stature, and facial scar, he is unable to find a girlfriend. Moreover, the girls at his school resent him due to his close association with Takahiko Satou, his handsome, popular, and tall classmate. In truth, Yoshida does not understand why Satou is so attached to him, given that they have nothing in common and barely know each other. Nevertheless, one of Satou's fans tricks Yoshida into discovering who Satou considers his "favorite"—the only person he will ever date. However, instead of uncovering the truth, Yoshida is caught off guard when Satou kisses him. The following day, the confused Yoshida suddenly recalls who Satou is: his gloomy, overweight elementary school classmate whom he used to protect from bullies. Immediately afterward, Satou reveals his true nature as a sadistic individual and confesses his love for Yoshida. Yet, being Satou's "favorite" might bring only more trouble to Yoshida's already complicated life.
