With rectangular coordinate system, my world is infinite.

Because no real number can express my persistence.

When I open my mouth upward, my pursuit of knowledge is like an endless long-term curve.

No matter how many storms you experience, you still don't change your true colors, and your true feelings will last forever.

No matter what random value we take in front, no matter how big the variance is in the future, I believe that the interval will be the smallest when we meet.
