Synopsis
“We’ll always be friends!”
At the end of one unforgettable summer, Hayato made a promise with his dearest childhood friend—who he thought was a boy. Seven years later, after transferring to a high school in the city, he reunites with that same friend. But now, Haruki has become a refined, graceful beauty admired by everyone as the school’s “flower on the hill.”
Yet, when alone with Hayato, Haruki smiles and laughs just like the old days.
From countryside to city life, from boyhood to girlhood, from growing hearts to changing bodies—some things have changed, but some promises never fade. A heartwarming and funny youth romantic comedy begins, spun around Hayato and his once “male” best friend.
