Shin Valencia is a senior high school detective student with a very private life. She has a heart full of sorrow and is craving revenge; life was a misery, and so is death. She wants to tear them apart, cry, and see them begging for forgiveness, even though forgiveness isn't in her vocabulary. Her feelings are burning with the will to do and get the justice she longs for; challenges and hardships are waiting for her to fail and once again drown. Not until two high school detectives came into her life, with whom she would solve the cases. They treated her as if there was a silver spoon on her, someone she could run to when she needed help, and that is when her demons calmed down; the fire in her heart was somehow disappearing. Will they make things easier or harder? Does revenge still stick in her mind after all? Can Shin still solve the last case?
