Timid and clumsy Atom has a crush on Mudmee, the girl who sits next to him in class. He despairs when he borrows her eraser and sees she's written the name of another boy—Kongthap—on it. To make matters worse, Kongthap sees his name on the eraser that Atom's holding and thinks Atom has a crush on him!
