[The title and blurb are provisional, but the core premise will stay the same.]
When little Natsume is young, he's adopted by the Sakamaki family. To outsiders, the Sakamaki mansion looks like a gloomy haunted house, but little Natsume doesn't see it that way.
His gentle eldest brother, disciplined second brother, cheerful third brother, and the other three brothers all take good care of him.
Little Natsume grows up surrounded by his brothers' love.
Until one day, he discovers that he's different from his vampire brothers.
He's actually... human!
What should he do... If they find out he's human, will they eat him?
Natsume is terrified, treading carefully around his brothers and doing his best to keep his human secret identity hidden.
The Sakamaki brothers have recently noticed that their adorable youngest brother keeps avoiding them. One after another, they go to check on him, secretly competing with each other, afraid someone else will take their place in his heart.
They've known all along that their little brother is human, but...
So what if he's human? They already love him so much they want to "eat" him.
The Sakamaki brothers have plenty of patience. They're carefully preparing a grand coming-of-age celebration for their little brother.
But when they plan to "eat" him on the day of the celebration, they discover...
Their beloved little brother has run away.
After learning about his brothers' plans, Natsume resolutely decides to run away from home.
The kind Fujiwara couple take him in when he has nowhere else to go.
Afterward, he transfers to a local high school and lives a leisurely, peaceful life in the countryside.
Told in two parts.
