Solving a system of equations is the process of finding solutions to a system of equations or determining that a system of equations has no solution. Solution, there is a unique solution or no solution. But you are my only solution.
When I first met you, you were a domineering girl who wrote the word "" on the blackboard. You were smart and proud, but you never looked at me seriously.
When I saw you again, your eyes were still shining with golden light, but your face was reddened by the equations.
In these seven years, what remains unchanged is your eternal inner tenacity, and it is also my constant pursuit of answers to you.
This time, please let me untie you, get close to you, and kiss you.
