[3][4] On March 15, 2021, 131 Label announced the release of the debut single album of B.I with a surprise teaser via their official YouTube channel.

He pledged to donate all the proceeds of the sound sources, recordings, and copyright fees to World Vision's domestic and international relief efforts for children in crisis.

[4][8][10] On May 4, 2021, B.I personally met with chairman Cho Myung-hwan at the World Vision Office (an NGO) in Seoul, to donate all the profits from the sale of 10,000 limited edition single albums of Midnight Blue (Love Streaming).

In addition, B.I promised to continuously donate all the revenue from the digital music sales and copyright fees that the single album would accrue.

His delicate vocals are able to convey a comforting assurance, though this is briefly broken during the song's midpoint with a sudden switch to a harsher rap voice that pierces the gentle cadence.
