Born Into The Aishi Family

Jokichi and Ryoba decided to have another child, this time no one has been forced into anything as everything felt genuine.

To their complete surprise however, the baby turned out to be a boy, which was mostly shocking to Ryoba since in the Aishi generation, only girls have been born so far.
Ayano Aishi, daughter of Ryoba and Jokichi, was only 14 when her new brother came to this world, how will their relationship develop? Will Ayano even tolerate her brother at all? will Y/N take more of his mother's genes and make him an infamous Yandere?

Yandere simulator grew somewhat fond to me while I was writing Ayano Aishi x Reader story, so I decided to write another one and try something different this time excluding the reader tag. There will be some things changed here and there so the characters won't be 100% exactly as how they are in the game.
So Buckle up, everyone!

About the cover, I'm planning to draw one of my own, but I don't know what to make exactly, so any suggestions will be highly appreciated!
