Title: Five Times Someone Assumed Oliver and Diggle Were Sleeping Together, and One Time It Was Mostly True
Canon: Arrow | DCCW
Pairing: John Diggle/Oliver Queen
Rating: Teen [PG]
Word Count: 4,315
Summary: Wherein Oliver and Diggle get along too well and sneak around together at all hours of day and night, and people make assumptions.
Recommendation: This is the first story I ever read in this fandom ages ago, and I find I like it just as much now as then. Subtle and understated with a really warm undercurrent.
