Nam derived her stage name "Eyedi" from ID (identity) in Korean, expressing her goal of people recognizing her when they listen to her music.

Nam became interested in music and dreamed of becoming a singer after joining the singing club in her second year of high school; however, she also wanted to become a fashion designer since she enjoyed art.

[6] Nam made her debut on July 19, 2016, under Bace Camp Studios with the single "Sign", which she cowrote with Loopy and Francis and coproduced.

[7] On July 21, she attended 2016 International Fashion Week in Zhengzhou to perform "Sign" as well as "Firework" by Katy Perry.

"Tomorrowland" was written for a suicide prevention campaign, and Nam stated that she "ruminated on the lyrics as I wrote them in hopes of giving strength".

The "Luv Highway" music video was supposed to be shot in Okinawa, but the schedule coincided with the Japanese holidays so she was unable to film there.

The name coll[a]ction is a portmanteau of "collection" and "action", with the desire for the release to express the feeling of capturing Eyedi's songs.

"Red" was described as "jazz-style soul classic R&B that embodies a deeper and more vintage sound than a trendy style".

[25] On October 21, Nam held her first solo concert "The Red Station",[26] performing her songs and also covering "If You Let Me" by Sinéad Harnett, "What You Do" by Chrisette Michele, and "Have I Told You Lately" by Olivia Ong.

[27] On June 6, Nam opened her YouTube channel Hey, Dream,[28] where fans submit stories via comment and she selects a winner whom she contacts.

Nam appeared on Studio Vibes, covering "Make You Feel My Love" by Bob Dylan with another participant.

Nam has named Stevie Wonder and Beyoncé as influences,[6] and lists Lee Su-hyun from AKMU, Taemin from Shinee, and Jay Park as artists she would like to collaborate with.
