Singer-songwriter MRCH debuted in 2019 with EP “Let’s march!”, and is best known for writing songs sung by TWICE, ITZY, NMIXX, and WOOAH, such as “Talk that Talk.”

Her stage name MRCH comes from the English “march” as in ‘on the march’, as well as March being her birth month. In Korean, 마치 sounds like the particle meaning “to be similar to”. She said that she likes the word because it represents “advancement”.
