You were childhood friends, but one day you were forced to move house to Tokyo and before you left you made a promise that when you grew up you would meet him in Okinawa.

and it's been twenty years since you moved, you haven't seen him at all in Okinawa.

He is always waiting for you on the Okinawa beach, hoping that you will come back and keep your promise to him.

he sat on a chair and looked at the sea sadly, every day he always waited here for you hoping you would come soon.

"Why hasn't he come yet? Has he forgotten me?"

with a sad voice and holding back tears he stared at the sea while continuing to wait for you.
