Shen Jixi was a young man who lived in a coordinate system. It wasn't until 7:31:21 in the morning of September, when the morning light illuminated Yu An's side face, that his world began to show errors.
Yu'an was like an unsolvable mathematical problem - the smile could not be quantified, the warmth could not be measured, but it made all Shen Jixi's precise calculations useless.
This is a confrontation between reason and intuition. It is a story about two teenagers redefining the variable "love" in the coordinate system of youth.
Intention: Love is the only variable that invalidates all precise calculations, and is the unsolvable formula that rationalists finally admit.
