There are many people who question SM Entertainment’s choice of leader for NCT 127. It is usually the eldest of the group who fills that position. Although Taeyong is not the eldest, he is appointed to be their leader.
Taeyong admits that he didn't expect to be given the role of leader but the responsibility came to him so naturally that he just embraced it. He excels through the pressure of communicating with every NCT unit but thankfully it has become easier over time. He credits the eldest of the group, Taeil, by giving him respect and advice which pushes him to be a better leader.
As a leader, Taeyong is responsible for every decision made in the group regardless of how insignificant it may seem. For example, deciding where to eat. He also relays group decisions such as camera positions and lighting to production staff when they are on stage. It is a breeze for him as he is creative and meticulous when it comes to the tiniest of details. He also finds joy in completing the schedules for the group.
SM Entertainment has commented that Taeyong was favoured as leader because he is always bursting with passion and enthusiasm for every performance.
It is clear that there is no one more suited to be the leader of NCT 127 than our perfect Taeyong. He has always taken care of his members and proven to be the best at rapping. SM Entertainment clearly made the right choice.
