Sanemi was sailing for a quest. A mission.
He missed his his wife,kanae and it's been days.. Months since sanemi and his crew where gone. One day the king himself was sailing.
He was running from Kokushibo, Kokushibo blocked the path of sanemi getting home.
when he came across a rock with a human(not) on it. Then he saw his wife there he wasn't sure it was them or just a siren in disguise so he decide to approach them to his surprise they notice his present
"Don't ya missed me..?" The siren disguised as Sanemi's wife said, as Sanemi thinks ,he came up that it's smart to play along so he can get to get home to his real wife and kid(you chose gender).
"More than you know.." he had responded back to the siren.. as he kept his act. Of actually believing it's Kanae.
