Norwegian Wood.

The profile also notes that Norwegian Wood (노르웨이 숲) originally debuted as a duo on October 2, 2014 with 취한 밤에 (featuring Hyobin). Another profile detail is that in 2018-2019, Soyeon left, meaning that the duo split. Additional background says that Norwegian Wood, however, is still active as a solo producer and composer, collaborating with other singers.
