Oh Hee Sun, previously known as Semmi, is a South Korean singer and former member of the girl group MATILDA. She made her debut in 2016 as the lead vocalist of the group with their 1st single, "Macarena". After releasing two more singles that year, all 4 members entered the survival singing competition "The Unit" in 2017 and she ranked 13th.

She made her debut as an actress with a role in the drama "The Best Hit" but music-wise, the group will not release anything new until the end of 2018 with their 4th single, "Between Fall and Winter". In late 2019, she announced that her contract with Box Media Entertainment had ended and she will not renew it. A few days later, the other 3 members made similar announcements and MATILDA quietly disbanded.

In 2020, she entered "Miss Trot 2" but was eliminated in the preliminary round.
