It's about how Hikaru and Megu-Chan hanged out and fell in love when they were pretty young. At the time Megu-Chan thought that hikaru was a guy bc she had shsort hair. Hikaru is very good at sports and very smart but still hasn't had a cellphone before. They found out that they are in the same highschool and then Megu tried to get use to the fact that Hikaru was actually a girl. Then they both found out that they still had feelings for each other. So they went out. The End
