Then on February 19, HUENINGKAI dropped a cover of 2002's mega-hit song 'Sk8er Boi' by Avril Lavigne on YouTube.
The color of his voice as well as the style of his singing contrasted the original version of the song.
However, he totally managed to make his 'Sk8er Boi' sound as if it was his own.
Regarding the cover, he received a lot of positive comments which included, "His voice goes so well with this song.", "He slayed it!", "He is so talented!" and so on.
Not long after his cover was released, Avril Lavigne once again took to her Twitter to share her thoughts.
She re-tweeted HUENINGKAI's cover of the song, and commented, "Amazing cover!" alongside an orange heart and skateboard emojis.
Then, she started following TXT's official Twitter account after that as well, making a great number of K-pop fans excited.
