Mileven

As Eleven ran for her life from a government laboratory tucked away in Hawkins, Indiana, Mike, Dustin, and Lucas find her in the pouring rain, in the woods while looking for their missing party member, Will Byers.

Mike was not aware of her telekinetic abilities when he decided to bring her into his home. As they noticed "weird" qualities about her, they questioned her upbringing, wondering why she isn't talking or why she has a shaved head. Dustin and Lucas were hesitant of Mike letting a strange girl stay the night despite his compassionate nature. When the boys left, Mike sat down with her and started talking to Eleven in hopes she would open up a little bit. When he asked her what her name was, she showed him her "011" tattoo. Instead of judging her for it, he was impressed.

As the journey went on for a bit longer, Eleven and Mike became extremely close after Hopper and Joyce set off to go find Will and save him from the upside down after Eleven had seen him in physic visions. While everyone else goes to either fight the Demogorgon or get Will the boys and Eleven stay in Hawkins Middle School. Mike tells Eleven after they defeat the bad men and the Demogorgon, Eleven would be able to come home with Mike, where Mike's mom could take care of her. Eleven mistakes Mike for being her brother, but Mike goes on to try and explain what it would be like instead. Fumbling with his words, he decides to kiss her instead. She is stunned, but happy.
