They had it all mapped out, printed in unspoken ink like a contract neither dared sign but both swore to uphold. Monica Calista Salvedra and Trevor Noah Cervado were the architects of their own arrangement- no strings, no questions, no claims. Just two bodies finding solace in the quiet hours, two lives running on parallel tracks that only converged when the lights went low. For months, they stuck to the script. But intimacy is a slippery thing. It started with lingering touches and glances that held too much weight. Then came the night the lines finally blurred. Wrapped in each other, the heat shifted from lust to something softer, something dangerous. A touch became a caress. A kiss became a promise they never meant to make. The contract was broken. The rules were dust. They were no longer just fuck buddies. They were completely Under the Influence-and there was no going back.

Roxanne Pantaleon isn't just a stunning face on the runway; she's a sharp Civil Engineering student who builds her dreams brick by brick. But balancing the spotlight with structural analysis becomes twice as hard, and twice as fun-when Brent Aldren Cervado is around. He's her senior, equally brilliant, dangerously handsome, and the master of pushing her buttons. Their relationship is a rollercoaster of witty banter, endless teasing, and moments that feel dangerously close to something more. One second they're arguing, the next they're sharing glances that make her forget how to breathe. When hate slowly turned into butterflies, can Roxanne handle the pressure of her career, her studies, and falling for the one guy who makes her heart race faster than she can calculate?

Cassandra Elyse Romero knows failure isn't an option. As the breadwinner of her family, her world revolves around studying hard and surviving. Distractions are a luxury she can't afford-until Matthew Cervado walks in. Brilliant, arrogant, and dangerously charming, he becomes her fiercest academic rival, constantly challenging her top spot. But as they clash in and out of the classroom, their sharp exchanges slowly turn into an undeniable tension. When rivalry blurs into something deeper, Cassandra is left with a choice, stay focused on her goals, or risk everything and cross the line for love. The line between hate and love blurs, replaced by an undeniable tension that neither can ignore. For Cassandra, letting him in means risking her focus, her plans, and her heart. Will she stay strictly in line to protect her future? Or will she finally cross the boundary and surrender to a love that burns as fiercely as their rivalry?
