2000, The turn of the century. Su Tianyi, who lives in 302, is a little sunshine that everyone loves, but she can't handle Gu Yanche upstairs!
He is the pride of heaven in the eyes of all the elders. His report card is always blinding, but he enjoys grabbing her ponytail and snatching her jelly.
"Gu Yanche, you hypocrite! Two-faced!" She accused angrily.
He raised his eyebrows calmly: "Su Tianyi, do you want me to 'tutor' your math paper, or do you want to give it to Uncle Su?"
She thought their war would never end. Until that day, when she was laughed at by others, the usually cold young man actually became jealous of her in public. He blocked the man in a corner and said in a voice so cold that he said, "The person I protect, is it your turn to make irresponsible remarks?"
It was also that day that she accidentally opened his notebook that no one would touch. It was densely packed with her name and portrait. On the last page, a line of sharp handwriting is shocking:
"Plan Day 3650, Su Tianyi, when will you be willing to look at me?"
It turns out that this "war" she thought was caused by him alone had planned the grand secret love of his entire youth.
