Jang So Jin, formerly known professionally as Soyee, is a South Korean singer, dancer, and former member of GUGUDAN (구구단). She graduated from Yeongdong High School and is enrolled in the Applied Music program at Baekseok Arts University.

Before debuting, she spent nearly 5 years as a trainee, including time at CUBE Entertainment and Plan A Entertainment.

She made her debut in June 2016 (using the stage name Soyee) as the group's main vocalist with their first mini-album, "Act 1. The Little Mermaid". After some initial success, the group began struggling to find promotional activities, and new releases were not as frequent. Jellyfish Entertainment (젤리피쉬엔터테인먼트) decided to put the full group on hiatus in 2018.

In December 2020, after two years of no activity, Jellyfish announced that GUGUDAN had officially disbanded.

She is currently not represented by any agency and has not had many credits since the group's disbandment.
