She was the girl everyone expected to be perfect The Principal's Daughter, raised with rules, honor, and a reputation she could never afford to break. Siya yung tipong dapat walang bahid, walang mali, at laging tama sa mata ng lahat. He was the boy everyone warned her about the campus bad boy with a sharp tongue, a reckless attitude, and a past full of scars he never talks about. Pero kahit gano'n siya kagulo, he was also the one who always topped the exams, the silent academic achiever who challenged her in every way. They were rivals from the start. Paligsahan sa recitation, bangayan sa debate, at tinginan na parang war zone sa hallway. No one expected them to fall for each other... not even them. But love has a way of crossing lines kahit yung mga linyang ipinangako nilang hindi nila tatawirin. Just when she finally let him in, nung naniwala na siya na there was more to him than the rumors and the walls he built... she discovered the truth. He betrayed her before he ever loved her. A bet. A dare. Isang kasinungalingang sinira ang buong mundo niya. Now they stand between hatred and longing sa pagitan ng sakit na iniwan kahapon at ng pag-ibig na pilit pa ring pumipintig today. Will she ever forgive him? Will he fight for her this time totoo na? In a world where love shouldn't exist between rivals, theirs might be the hardest lesson of all-isang kwentong patunay na minsan, ang pinakamahirap na laban ay yung laban ng puso.
