Jiang Ran had lived for eighteen years, always thinking there were only three women in his life: Su He, the neighbor girl who raised him like her own son; Zhou Nian, his childhood friend who had beaten him up since they were little; and the mysterious campus beauty Jiang Ci, who was always sleeping in the back row of the classroom.
Then, in the summer of his senior year of high school, everything began to spiral out of control.
On his birthday, his sister-like neighbor Su He got drunk and pinned him to the sofa, her eyes frighteningly red. "Xiao Ran, I've waited ten years for you to grow up. If you dare to like someone else, I'll lock you up at home and keep you all to myself for the rest of your life."
His childhood friend Zhou Nian smashed the wall beside him with a punch. Blood seeped from her knuckles as she grinned like a madwoman. "Jiang Ran, you belong to me. You always have. If anyone gets close to you, I'll make them disappear."
The campus beauty Jiang Ci handed him a note with just one line on it: "Last night I dreamed you died. I killed you. When I woke up and realized it was only a dream, I was a little disappointed."
Only then did Jiang Ran realize that every girl around him was a yandere.
Worse, they all thought they were the only one for him.
And Jiang Ran's task was to survive his senior year between three obsessive, possessive, completely unhinged women.
