For Zidane Sevilleno, math was never a problem, it was the solution. Trigonometry, functions, sequences... He can easily solve all of those. But despite being an excellent student, the heavy pressure of perfection, like being trapped inside an inequality-where the variables are expectations, and the solution is never enough. He can plot every curve and solve for x without blinking. Yet he struggled with the one unknown no formula could solve: life beyond numbers. And there is Mireille Marquez, a Psychology student who didn't seek the right answer, but the right question. She didn't care for solving for x, she wanted to know why the heart reacts the way it does. When Zidane saw life as something to be solved, Mille saw it as a story to be felt. Could he learn that life isn't always about exact answers... but about learning to live beyond the limits of logic? Because sometimes, the heart's greatest equation isn't meant to be solved... but lived. Maybe... Just maybe, "I x² - |x|y + y² < 1 ... you." It wasn't just an inequality at all, it's the language of love and the shape of a heart Zidane has yet to understand.
