Apples
When the fourth mizukage first kissed her, he thought she would taste bitter such as grapefruit. However he was pleasantly surprised she tasted sweet like apples. Apples that would rarely grow in the land of snow. She reminded him that he wasn't alone as he thought he was, and she was going to stand by him thick and thin.
Natsu sukai never expected to be kissed by her future mate/fiance due to thier arranged marriage before she was even born. He was surprisingly gentle, and he tasted like green tea. Her favorite. She was constantly aware they were due to marry to keep the alliance between mist and fire. She was falling little by little in love with Yagura. From his gentle smile to his skills on the battlefield.
Sarutobi smiled knowing through his crystal ball. He knew that his fellow kage Yagura will protect his sunshine with his life. He can rest easy knowing that she was untouchable to danzo or any of the council who wanted to get thier hands on her heritage. Now he wonders when he can expect future great grandchildren from the two of them.
