We can say Mark is one of the member who really know and see Taeyong's history in 127 or even in SM. They training as rapper tgt, write lyrics together since young, discussion about NCT music and the performance, and debut in the same unit and adore each other.

Since debut together untill now, Taeyong never change his mind that Mark is the cutest.
