Y/N Henderson, Dustin’s older sister, meets Steve Harrington, Dustin’s best friend, for the first time and immediately falls for him. The catch? She’s not subtle. At all. In fact she says everything outright from the moment she meets him. She’s so blunt he thinks she’s joking. For a long time. They bicker when the group hangs out. She flirts, he thinks she’s ridiculous, Dustin finds it all hysterical. Yet he can’t help but blush because as much as he hates to admit it, he fell too.
