[A seemingly obedient but secretly yandere younger schoolmate X a seemingly gentle but actually extreme and cold older girl]
During her freshman-year winter break, she returned to her old school to visit a teacher who had once helped her, and happened to meet a fair-skinned, clean-cut younger schoolmate.
The younger boy said, "Hey, schoolmate, want to add me on WeChat?"
She said, "Sorry, I'm already a college freshman."
He smiled. "Then let's start over. Big Sis, how about we add each other on WeChat?"
The younger boy was clingy, but considerate and well-behaved.
"Big Sis, I don't like basketball or games. I only like you."
"Big Sis, I've never dated anyone before. I'm completely innocent."
"Big Sis, when will you finally like me?"
"Big Sis, I'm only three years younger than you. I'm not a kid anymore."
Cheng Jian met Ni Yaoyao in his second year of high school. She was so tiny,
and though she wasn't particularly pretty, she somehow caught his eye.
He really liked her so much.
Ni Yaoyao never thought she'd date a younger man, let alone a schoolmate three years her junior.
She never imagined the younger boy would turn out to be yandere, either.
"Yaoyao, you and I are the same kind of person. We were born to be together."
"So I'll stay by your side, for a long, long time."
