She's totally gonna have a BF

It's no secret that a lot of couples look like siblings. A considerable portion of the population is attracted to people who look suspiciously similar to themselves. The popular Instagram account Siblings or Dating is dedicated to speculating on this question, posting pictures of two people who look alike, polling their followers on whether they think they're siblings or dating, and revealing the answer. This speculative game is all in good fun, until it gets way too real.
