Hanna Borysivna Korsun, known professionally as Maruv, is a Ukrainian singer, composer, poet and producer. She lives and works in Kyiv. Korsun used to be part of the band Maruv from February 2017 to March 2018. It was the successor of the band The Pringlez. Later, Korsun gave an interview in which she explained that from then on she would be working on her own under the pseudonym.

In school she studied music and dance. In 2014, she graduated in a non-musical subject from the Polytechnic Institute in Kharkiv. Despite this, Popeliukh participated and reached the final of the contest The Voice of Ukraine. She is married to Oleksandr Korsun, whom she met while studying at the institute. Oleksandr was the PR manager of The Pringlez. The team included a drummer, guitarists, a songwriter, and also a photographer and sound engineer.

In 2015, the group represented Ukraine at the New Wave competition. In addition, one of their songs – "Easy to Love" – made it to the final of the Ukrainian selection for Eurovision 2016.

In 2017, the band changed its name to Maruv. In addition to this, the group members decided to change the concept of their work. The old group name was left in the past, as well as their pop-rock performance style. They decided to leave behind their “teenage” creativity, and adapt a modern and popular style. In May 2017, the band released its debut album, Stories. It includes seven tracks written in three languages – Ukrainian, Russian, English. On 23 September 2017, the band presented the album at a concert at their hometown of Kharkiv.
