A Neat and Pretty Girl at the Transfer Destination Was a Childhood Friend Who Used to Think That She Was a Boy and Played With Her., 転校先の清楚可憐な美少女が、昔男子と思って一緒に遊んだ幼馴染だった件, Tenkousaki no Seiso Karen na Bishoujo ga, Mukashi Danshi to Omotte Issho ni Asonda Osananajimi datta Ken, Tenkosaki: The Neat and Pretty Girl at My New School is a Childhood Friend of Mine Who I Thought Was a Boy

Recently, I encountered my childhood companion once again, and to my surprise, she had transformed into a stunning and pure young lady. When we last met, Hayato, it was like seeing Haruki for the first time all over again. Although our friendship dates back to when we used to frolic in the mud together in the countryside, I couldn't help but notice that there was no sign of the impudent youth I remembered from before. However, as soon as she saw Hayato, she shed her coat and reverted to her old crude demeanor. Despite this change, our bond remains unaltered.
