Aspa, another "Sterek" fan adds, "The actors' chemistry is one thing. Also Derek being broody, badass werewolf having to deal with awkward, human sidekick Stiles is fun."

For example, in the “Teen Wolf” fandom, many fangirls have an intense love for Sterek (Stiles/Derek), two single characters who are not in a relationship and supposedly straight.
As for the ships, currently the three most popular on AO3 are “Johnlock” (Sherlock Holmes/John Watson from Sherlock), “Destiel” (Dean Winchester/Castiel from Supernatural) and “Sterek” (Stiles/Derek from Teen Wolf).

Some shows have released official promos that play up the fans' favorite slash couples to court fans, most recently Hawaii Five-O and Teen Wolf, whose showrunner began to write the show itself in a slashy direction when he became aware of the popularity of “Sterek,” the slash pairing of sidekick Stiles and alpha wolf Derek.
"Teen Wolf 'Sterek' fans, we've read your (hundreds and hundreds of) comments and admire your passion," EW.com responded. "The reason Sterek didn't make the category is because it's not an acknowledged will-they-or-won't-they storyline."
This controversy led the gay entertainment news site AfterElton.com to start an annual "slash madness" tournament. Sterek won the first.
