Sarah Yeeun Lee was born on May 25, 1995, in Seoul, South Korea, to two Korean parents. When she was six, her family moved to Germantown, Maryland, United States. She took lessons on piano and guitar. Her parents, devout Christians, paid for tutoring to ensure sure she would perform at church services. She graduated from Northwest High School in Germantown, Maryland in 2014, then from the University of Maryland, College Park in 2018. In a 2020 interview with The Diamondback, Ami described her musical process during the COVID-19 quarantine: "ItâÂÂs mostly virtual sessions. Every session is different with each producer but, you know, trying to just make it work. And itâÂÂs been successful so far."
In 2019, Ami filmed the visualizer for her breakout single "Snowcone" with a budget of under $100. That led to her signing with Visionary Records.
The official music video for "Freak" by Sub Urban, featuring Lee, was released on March 13, 2020, alongside Sub Urban's EP Thrill Seeker.
