LIGHTSUM - Meet The Members

Over the last few years, the world has seen a paradigm shift in power to influence masses from the hands of the West to that of the East. East Asia, especially, has completely revolutionized the way we consume pop culture content. One country, in particular, stands out distinctly from its contemporaries. We are referring to South Korea’s powerhouse of talent when it comes to the country’s billion-dollar entertainment industry. Be it music, television, or movies, the Koreans have found a global audience everywhere. Truly, the Hallyu Wave has overtaken the world. In our article today, we will introduce you to the members of a new K-pop girl group – LIGHTSUM. We will also explain the profiles of the members.

CUBE Entertainment


The summer months are often very busy in the K-Pop industry, as most new groups debut around this time. CUBE Entertainment is one of the biggest artist management industries in South Korea. They manage groups such as BTOB, (G)-IDLE, CLC and Pentagon. This time, CUBE is all set to debut a girls group on the 10th of June 2021. LIGHTSUM happens to be the only group in the agency where all the members were born after the year 2000. LIGHTSUM is all set to debut with their first single titled ‘Vanilla’. Given the success of their seniors from the same agency, LIGHTSUM is also expected to make a great name for themselves.
