Millie Bobby Brown and Finn Wolfhard play pals Eleven and Mike Wheeler on Netflix’s Stranger Things, and their friendship is just as cute in real life. Not only do they always seem to have the best time together, but fun fact: Finn was actually Millie’s first kiss. “It was definitely strange.

It makes sense for the storyline.'” In honor of their adorable bond, take a look at some of their cutest moments together.
