Troye Sivan explained the background to the song in a Genius interview
"Love is a very scary thing. Especially if you're not sure yet if the other person loves you back. It's a really scary place to be in. As exciting as it is, there's a lot of vulnerability in it, and there's a bunch of reasons why people don't let themselves have that. For me, with this song, it was a bad time, it was a really bad time. But, what can you do?"
