Code and crimson

Caihong is a final-year computer science student who lives by logic and code, afraid of the messy unpredictability of love. She keeps to herself, balancing late-night coding sessions, a part-time internship, and quiet evenings with her best friend, Biyu. But her orderly world shatters when she crosses paths with Dexing - a ruthless, charming young mafia boss who rules the city's underworld with an iron fist and an icy demeanor.

Despite their stark differences, Dexing finds himself drawn to Caihong's quiet strength and sharp mind. As their unlikely romance blossoms, dark secrets from the past emerge. Caihong's father, once a brilliant programmer, vanished after working on a dangerous project called Hydra - a shadowy system that Dexing's mafia family now controls. Together, Caihong and Dexing uncover a conspiracy that threatens to destroy them both.

With time running out and enemies closing in, they must learn to trust each other and face their fears. In a world ruled by power, deception, and cold steel, can love be the code that breaks through every barrier - or will their pasts tear them apart forever?
