Lin Ran took Xiao Xun in when she was little. Xiao Xun had promised from childhood that she would marry Lin Ran one day, until... everything changed on Xiao Xun's seventeenth birthday.
Lin Ran: Xiao Xun, you promised you'd marry me. Why? Why?
Xun: You're so strange. That was something I said when I was a kid.
Even if she had to resort to more extreme measures, even if Xiao Xun became foolish because of it, even if she forgot all the memories she had made with Lin Ran, Lin Ran wouldn't regret it.
Lin Ran: Be good, Xiao Xun. It's time for your shot.
Miss Xun, a pure white little lotus, versus Lin Ran, the dark queen. Two yanderes against two yanderes, both taking the lead. A love no one understands.
