The number of murders in recent suddenly increase. The murderer ways of killing leave the authorities baffled and unsettled. The serial killer loves draining the blood of the victims that even a single trace of blood was not found and always left some kinds of codes and puzzles. The highest authority decided to turn over the case to the special unit and the newly hired cryptographer was added to the team. Irish Gomez was the newly hired cryptographer. She didn't expect that a weird case will be used for her probation period. What makes the matter worse, she was partnered to a cold and aloof man, Albert Simon, with an unusual habit of doing work in the nighttime and can't be found in day time. Facing the pale white handsome face of this man, Irish's heart skipped a beat. She slowly swallow her saliva to ease her nervousness. A blush color her white cheeks that make her more alluring. She didn't expect this aloof man to have a perfect body. Seeing her motionless and just staring at him. The man smiled revealing a perfect set of white teeth that make the young woman baffled and her smooth forehead creased. "Why does your canines so pointed and it seems it growing?" "And... your eyes it became red..." The man trapped her inside his arm and the wall. His handsome face slowly approach her. Whispering in her ears, he asked with a hint of a smile on his deep voice. "Same questions to you honey, why does your eyes keeps changing a color?" "..." "They said it was a sign of an excitement, a fear... and... a lust." "..." I'm doomed I forgot to wear my contact lens.
