Oh is a nerd who is considered the school's biggest loser. He hates the school because he is often bullied and mocked by his peers who call him Mushroom. Oh is mainly bullied by Copper, In and their gang of bullies. However, even though he hates the school there is only one person who motivates him to come back every day and that is Peach, the school's prettiest and kindest girl. Sadly, Peach is dating Copper. Sun is the new kid at school. Due to unlucky circumstances he becomes friends with Oh. With Sun being friends with the school's loser he is often picked on by Copper and In. But something about Sun makes In feel different. Can the biggest school's nerd end up dating the popular girl? Can a bully fall for the new kid?
