Seenroot (Korean: 신현희와김루트; RR: Shin Hyun-hee wa Kim Root; lit. Shin Hyun-hee and Kim Root) was a South Korean musical duo, signed under Kakao M's indie sub-label Mun Hwa In. The pair's debut mini-album was released in 2015. The record's lead single "Sweet Heart" did not see success until two years after its release, when a broadcast jockey sang the song in midst of live streaming and became a viral video. It led the song to peak at number 13 on the national Gaon Digital Chart, where it sold nearly 1.3 million downloads by the end of 2017.
