February 14th was never about love.

In a modern city drenched in pink lights and public confessions, an ancient celestial treaty activates at midnight. Angels descend to amplify human emotion and harvest the energy it produces, while demons roam freely to destabilize feelings and push the surge higher. The ritual sustains a hidden seal beneath the city — one that must never break.

When unexplained cardiac deaths flood the ER, night-shift nurse Elena Navarro begins noticing the pattern no one else sees. Hearts are failing without physical cause. Security cameras glitch. Figures appear where no one stands. As the Valentine’s celebration intensifies, the emotional amplification exceeds safe limits, threatening to rupture containment.

Caught between a calculating angel who seeks to restore balance and a perceptive demon who questions the system, Elena must uncover the truth behind the harvest before the city’s devotion becomes its undoing.
