Luca, the Rizzoli family's top assassin, was taken in by the young master Alessandro for ten years, willingly serving as his most obedient weapon, his deep-seated love never daring to be spoken. Humiliation from a forced marriage and death sentences followed one after another, leading him to mistakenly believe he was merely a disposable tool. He was also shocked to discover he was the orphan of his enemy, and that their ten-year encounter was all premeditated. Alessandro, using indifference as a cover, secretly protected him until news of Luca's death in a fire arrived, at which point he was overcome with remorse and lost control.
