Marshmello and Halsey indirectly came out announcing a collaboration on April 29, 2020, through their social media by posting a flower visual each and the caption "friday". The two musicians went on to reveal the song title and cover art, a painting of a flower with a pink sticker, a day later through their social media.

Musically, "Be Kind" is an "emotional" EDM song that sees Marshmello and Halsey "[exploring] trust issues and [reinforcing] that it's OK to be vulnerable with someone you love." In terms of music notation, "Be Kind" was composed using ⁴
₄ common time in the key of E major, with a tempo of 94 beats per minute. Halsey's vocal range spans from the low note F♯3 to the high note of C♯5.

A music video was released on YouTube on June 28, 2020. It was directed by Hannah Lux Davis. The video begins with Halsey sitting in a chair and dancing around a large grey room. Later she appears dancing in a seemingly digital utopia full of flowers and sakura trees. At the end of the video, she awakens back in the grey room where she attempts to communicate with Marshmello, who is seen on a small screen directly in front of her. As of October 2023, the video has over 109 million views.
