Unique as the root of a linear equation.

It extends like a straight line.

Like a circumscribed circle, heart to heart

My love for you

Like a regular triangle

Even if there are five hearts, they are heart to heart and single-minded.

Our lifeline, career line, love line

It will be like a three-line and an isosceles triangle.

If one day, there is a negative number in the root sign.

If one day, a of quadratic equation is equal to zero.

If one day, there are a finite number of natural numbers.

If one day, the vector has no direction.

If one day, you and I become parallel lines.

If one day, our love becomes an empty set.

I also want to say that I still love you.

Just like the inverse proportional function

Even if it can only be infinitely close.

Always guarding you.
