Mnet’s Produce X 101 recently shared a double-speed version of “Monday to Sunday” which showed the members scurrying about trying to keep up with the tempo.
In the midst of all the madness, Lee Sejin drew particular attention with the big smile on his face as he attempted to complete the very fast choreography.
Despite being absolutely exhausted, he managed to keep that smile on his face from beginning to end while also nailing most of the choreography.
What really stands out is how big and contagious his smile was throughout the performance.
The closeup shots of his smile are enough to make just about any viewer smile back.
