She's perfect in front of everyone else, then she talks to you and drops the whole act like a costume she's been wearing all day. The comedy lives in that gap, in how she's only ever crass and real with one person, and he's too stunned to realize it means something. By the time he gets it, the audience already did two episodes ago.

Hayato transfers to a high school in the city and meets Haruki, the refined, graceful beauty every boy there admires. Seven years earlier the two played in the mud together in the countryside, and Hayato believed Haruki was a boy. Now he learns she is a girl. With everyone else she keeps up her polished image, but around Hayato she drops it and turns as crude as she was back then. Their old promise to stay friends holds, and their feelings slowly grow into something more in this romantic comedy based on a light novel series.
