"Be Sweet" is a song by American indie pop band Japanese Breakfast, released on March 2, 2021, as the lead single from their third studio album Jubilee. The band's lead vocalist Michelle Zauner co-wrote the song with Jack Tatum, the founder and lead singer of the indie rock project Wild Nothing. Zauner's bandmate, Craig Hendrix, encouraged her to compose arrangements for Jubilee; the two of them, along with Tatum, worked on the track's production.

Japanese Breakfast is an American indie pop band headed by musician Michelle Zauner. Zauner started the band as a side project in 2013, when she was leading the Philadelphia-based emo group Little Big League. She has said that she named the band after seeing a GIF of Japanese breakfast and deciding that the term would be considered "exotic" to Americans; she also thought it would make others wonder what a Japanese breakfast consists of.
