Catch me if you can, Liam (a Sherliam fanfic)

Sherlock Holmes and William Moriarty have been the best of friends for a long time now, and it's no mistake that the blondie may have developed feelings for his friend. To cover up for this, William decides to introduce his friend to a girl who asked for his assistance in getting with Sherlock. Reluctantly, the bluenette agrees to try spending time with the girl but soon realizes that he's not straight at all. Not wanting to hurt either the girl's or William's feelings, he hesitantly agrees to become the girl's boyfriend, and soon enough fiance. Wanting nothing but to get away from the situation and to stop having to act like he wasn't in love with his friend and instead the girl, he seeks his brother's assistance. William, hoping to end his own suffering, is ready to finally confess to his blue-haired friend but before ever saying goodbye, Sherlock moves away.
