Ahn Hye-Jin, more known as her artistic name, Hwa Sa, She is a South Korean artist part of the girl group MAMAMOO, and is in charge of the group rap's and vocals. She born on July 23, 1995 in Jeonju, Jeollabuk-do South Korea. Where she lived with her parents and her two elder sisters. She graduated from Wongkwan Information Arts High School. 

Since young age Hwa Sa knew that she wanted to be a singer. She states that Beyonce was a huge inspiration to her. Hwa Sa mention that after hear someone said that "She was unique and good at singing but was fat and not pretty'', she went home and watched videos of Beyoncé performing all night to comfort herself. 

Hwa Sa has been one of the most controversial artists in the K-pop industry, since she has been one of the most recognized feminine "K-pop Idols" in braking stereotypes, breaking those beauty standards that South Korea has been trying to impose during many years over its artists. 

She has been judged by how she looks, how her body and personality doesn't fit with the image of a "good idol". That's why every time she is on stage she tries to show how she really is by dancing, singing, and wearing what she wants to express to her audience.

Hwa Sa doesn't have a specific dance style because her main focus on her career as an artist is singing, but that doesn't stop her to dance on her videoclips and her performances on stage.

For Hwa Sa dancing is to be free. 

Dancing is not only part of her job, dancing is a way to tell the world she is strong. Even though that her culture is very conservative, and doing "obscene" movements in her performances are very bad seen, she still doing it because she doesn't care at all about the hate that she is is going to receive, because what the she wants for her audience is to show them that they as humans beings are free to move their bodies the way they please.

Even though many of her actions on stage and outside of it had cost her plenty of critics from internet users, and South Korean media, she just gets stronger, and every time she has the opportunity to advocate for women respect and body positivity she does it no matter what others would say about her. 

 “I love the line [in “Maria”] that reads, ‘Why do you keep struggling ― you are already beautiful. I think this part brings comfort and energy to the listeners.”- Hwasa
