Hey, did you know? If you write your crush's name on your eraser then use it up, he'll fall in love with you! Hey, Satou-kun dropped his eraser...Ah ha! Itou-san's name is written on Satou-kun's eraser! That must mean...Satou-kun...Satou-kun's in love with Itou-san! Huh? You don't remember writing it? Oh come now...Hmm? Oga-chin? What's wrong? It's not Satou-kun's handwriting? H-How can you tell?
