Story

Biography

Yebin is a South Korean singer-songwriter best known as a member of the girl group DIA, and one of the more musically hands-on idols of her generation — she has written and composed several of her own group’s songs rather than simply performing them.

Born Baek Ye-bin on July 13, 1997, in Chuncheon, Gangwon Province, Yebin grew up with her parents and younger brother in a household connected to the local beauty industry; her mother’s hair salon in Chuncheon is even named “DIAHAIR” after her daughter’s group. She trained at Calip Dance Academy and was once slated to debut with Ensoul Entertainment’s Project A before joining MBK Entertainment (later PocketDol Studio) as the final addition to DIA‘s original seven-member line-up in 2015.

As DIA‘s lead vocalist, Yebin quickly stood out for her songwriting, co-composing tracks such as “Not Only You But Spring” and contributing to “Will You Go Out With Me?” In 2017, she and fellow member Somyi took a detour into the survival show The Unit, where Yebin placed second among the female contestants and went on to debut with the resulting project group UNI.T in 2018.

After returning to focus on her own artistry, Yebin released the project single “Yes I Know” in 2021, and — following DIA’s move into an indefinite hiatus in 2022 — signed with YamYam Entertainment, where she released her first independent single, “Contrail” (비행구름), in 2023. Fans of K-pop idol biographies and DIA discography alike continue to follow her ongoing solo music career.

The Fandom

Fan Club & Fan Name 💜

Official Fan Name
AID
AID is the official fandom name of DIA. Spelling the group's name backward, it stands for the idea that fans and the group always face each other and support one another, the way the English word "aid" suggests. MBK Entertainment revealed the name alongside the group's early promotions.
Official Fan Color
AID Blue & DIA Red
DIA's fan colors pair a deep AID Blue with a bright DIA Red. The agency never released official Pantone codes, so these shades are the closest common approximation used across fan communities and merchandise.
Official Light Stick
Yambong (Diamond-Shaped Light Stick)
Nicknamed the "Yambong" by fans for its rounded, yam-like shape, this stick was first sold as a temporary light stick. Because PocketDol Studio never issued a formal follow-up, it became the group's de facto official light stick by default.
Fan Community Platform
Instagram & Daum Fan Cafe
DIA and its members mainly connect with AID through the group's official Instagram account and the long-running Daum fan cafe "officialdia," alongside members' individual social channels.
