Hwang Ji Won, known previously as Viva and Sunn, is a South Korean singer, dancer and former member of GOOD DAY and CIGNATURE.

She made her debut in 2017 as part of GOOD DAY (using the stage name Viva) with their 1st EP, "All Day Good Day". Months later, she entered the singing survival show "The Uni.T" and finished in 29th place, so she did not qualify for the project group formed afterwards. As she was in the competition alongside 3 other group members, the group was not able to promote and was not successful, so they quietly disbanded as C9 Entertainment began planning their next girl group.

She re-debuted in 2019 with CIGNATURE (using the stage name Sunn) as their main vocalist and lead dancer with their 1st single, "Nun Nu Nan Na". In 2021, the agency announced she did not renew her contract and that she decided to leave the group without providing a specific reason. She opened a YouTube channel with fellow group mate Kim Ha Eun (previously known as Ye Ah), but the channel has no uploaded material. She was also part of pre-debut group ALDL, but it seems they have disbanded before debuting.
