Yes, Soobin is the leader of the K-pop group Tomorrow X Together, also known as TXT. He was chosen as the leader before the group debuted because all the members and staff at Big Hit Entertainment, now known as HYBE, voted for him. This decision was made through a democratic process where everyone had a say in who should lead the group.
Soobin was selected because he is a good communicator and always puts the needs of others before his own, which makes him a comfortable person for the other members to talk to. Although he initially thought Yeonjun would be a great leader due to his responsible nature, Soobin himself was chosen unanimously by the group and staff.
As the leader, Soobin plays a crucial role in guiding the group and ensuring they work well together. Despite being a shy person initially, he has grown into his role and is highly respected by his members for his leadership qualities. Soobin also admires other leaders, like BTS’s RM, who he believes sets a high standard for leadership in K-pop.
