At the end of one childhood summer, Hayato made a promise with his precious best friend.
Seven years later, after transferring to a high school in the city, Hayato is reunited with that childhood friend—
Only to discover that Haruki has grown into a graceful and beautiful young woman.
Known at school as an unattainable beauty, Haruki seems completely out of reach to everyone else. Yet whenever she's alone with Hayato, she smiles and talks to him just like she did in the old days.
The countryside and the city.
A boy and a girl.
Hearts and bodies that have changed with time.
Though many things have transformed during the years they spent apart, some feelings—and the promise they made—remain unchanged.
Thus begins a youthful romantic comedy about reconnecting with a childhood friend who was once a “boy friend” in the most literal sense.
