The secret between us - Sherliam Fanfic (Sherlock Holmes x Willam Moriarty)

Sherlock and William have been secretly dating for weeks, a relationship that began unexpectedly after their meeting on the train. Their connection grew quickly, and despite their feelings, they agreed to keep it hidden from everyone.

As time passes, the weight of secrecy becomes harder to bear. William starts making excuses to his brothers, disappearing for hours, sometimes spending entire nights away with Sherlock. Sherlock, meanwhile, struggles with his addiction and the lack of new mysteries to solve. Frustration builds as he faces the absence of cases to challenge his mind, causing his anxiety and self-destructive tendencies to grow.
What Sherlock doesn’t know is that William’s life is far more complicated than he imagines. Beneath the calm façade, William is the feared Lord of Crime—a secret that could shatter everything between them if discovered. The guilt of his double life weighs on him, and the more he cares for Sherlock, the harder it becomes to hide the truth.

As their relationship deepens, so does the tension. Their secret lives, personal demons, and the looming risk of exposure threaten everything they've built. Will their love survive the dangers of the secrets they keep?
