Ahn Hee-yeon was born on May 1, 1992, in Seoul, South Korea, but her family and friends all called her Hani from a young age.

In 2015, she appeared in Mad Clown's music video for "Fire",[12] and entered the main cast of JTBC's Off to School[13][14] and Crime Scene.

[15][16] Hani was also chosen to present a new KBS beauty show, A Style For You along with Kim Heechul, Goo Ha-ra and Yoon Bora.

Hani surprised the panel of judges and an audience with her rich and husky voice (mostly due to the higher vocal range used as a vocalist in EXID).

[23] It was later revealed that the song's title is "Honey Bee", and is of the pop soul genre, incorporating 808 bass and saxophone.

In May 2019, Banana Culture announced that Hani and Jeonghwa would not be renewing their contracts, and EXID would go on hiatus after finishing their tour in Japan.

[25][26] In October 2019 it was announced that Hani has signed with Sublime Artist Agency and that she would be making her film debut with her given name Ahn Hee-yeon.

[30] On August 11, 2020, Hani was announced to be starring in another web drama, How to Be Thirty, alongside Jung In-sun, Kang Min-hyuk, Song Jae-rim, Cha Min-ji, and Baek Sung-chul.

[32][33] On July 20, 2021, Hani was set to star in JTBC's upcoming series, Idol: The Coup, but due to her being tested positive for COVID-19, production was postponed until further notice.
