A Study of Lovers (Johnlock fanfic)
John couldn't shake the feeling that something is wrong with Sherlock as John was battling with himself on his reoccurring thoughts of the detective, which he constantly shook off and seemed to think it was nothing.
He's been acting strange towards the army doctor. But once John starts using his own methods of deductions, what he finds of Sherlock; and himself, will leave him shocked. But strangely relieved.
