Lu Zhuoyun has a secret no one knows: a number appears above the head of everyone who enters his field of vision.
The number represents their danger level, from one to ten, clearly showing how much malice they feel toward him.
His father, who angrily curses him, has a nine. The classmate who deliberately shoves him has a ten. Lu Zhuoyun is extremely cautious, following these numbers and a little intuition to survive in the cracks as life beats him down.
He told this secret to only one person. When his mother worked as a housekeeper for the Shen family, the young master was his only friend. The boy always called him stupid and addressed him in a stiff, formal way as "Camel."
But later, a murder took place in the Shen household, and the young master mysteriously disappeared. Lu Zhuoyun moved away from the city with his mother, and many years passed in the blink of an eye.
When he ran into the young master at school again, the other boy stood beneath the shade of a tree, his face pale and his eyes dark and still. He smiled faintly at him. "Camel, long time no see."
Lu Zhuoyun couldn't help taking a step back, alarm bells ringing in his heart, because he saw a dazzling, blood-red "∞" above the boy's head.
*
Lu Zhuoyun never knew that the person he had desperately searched for back then had been buried beneath the flowering tree outside his window all along.
"Possession is the most dangerous kind of intimate relationship."
1. The love interest is dead, and isn't human.
2. ∞ means infinity.
