"What happens when the person you hate the most... is also the one who understands you best?" Selene Navarro is all about logic, numbers, and blueprints. As an engineering student, she has no time for distractions-especially not the annoying, arrogant architecture student living next door. Cairo Emilio Velasquez is all about art, chaos, and breaking rules. He sketches buildings like dreams and flirts like it's his second language. The problem? Their families are mortal enemies. Their houses are right next to each other. And their hearts? Slowly betraying them both. In a world where love shouldn't exist between them, what if falling for each other is the one thing they can't control? Enemies. Neighbors. Lovers. Sometimes, the thin walls between hate and love are easier to break than they thought.
