Suffering from mental illness, he sets up routines and waits for the attack to be discovered. He likes to reveal his weaknesses and shadows little by little.
The best HP fanfic I have ever seen, original work, the CP is Draco, their love has overcome many difficulties and tests, and the plot is very true to the original work.
Pure love, the plots in each world are very interesting, especially a beauty who is imprisoned after a tragedy in the entertainment industry and suffers miserably.
