BOL4

BOL4 (Hangul:볼빨간 사춘기, also known as Bolbbalgan4, pronounced Bolbbalgan Sachungi) is a South Korean Indie-pop sololist (formelly duo) under Shofar Music. They debuted with an mini album named Red Ickle with a title track named "Fight Day" on April 22nd, 2016.

The duo went on a temporary hiatus due to Ahn's music classes requirements in the first half of 2018. BOL4 signed with King Records and debuted in Japan on June 5th, 2019, with the mini-album Red Planet (Japan Edition).

on April 2nd, 2020 Shofar Music announced that Jiyoon had left the duo, and Jiyoung will continue to promote as BOL4.

History
Jiyoung and Jiyoon were both raised in Yeongju city, Gyeongsang, and were classmates. They had previously competed SuperStarK6 in 2014. Since they were young they had dreamed of becoming singers. The name of their duo was built on the grounds that they wanted to make the kind of pure, honest music that can only be found in adolescence. Jiyoon portrays the "blushing" part of the name because she is often shy, while Jiyoung portrays "youth" because she acts like an adolescent girl.
