Yoshida is ugly, and, other than two loyal (yet also ugly) friends and the sadistic year-mate, everyone hates him. He gains this hostility by, other than being extremely ugly, seeming to hog the attention of the school's heartthrob Satou. What the girls of the school don't know is that Satou uses Yoshida as an excuse to refuse girls, and that Yoshida is only a poor victim.
Disregarding his poor use of Yoshida, Satou likes him very much; as he is actually a class mate from Yoshida's elementary school. As a 'strong man with a sense of justice' and the tallest in the class Yoshida was actually popular, and saved the fat kid of the class,Satou, from bullies.
Now in highschool, because of this Satou seems to have decided that Yoshida is his 'favourite'. With hard childhood, the now sadistic Satou causes much pain for Yoshio.
