This proves that no matter what fandom your part of and you begin to watch videos like this, you realize how hard each group works to become successful at how hard the newer groups are working and realizing that the older popular groups had/&still are going thru as well. This helps you learn how to respect every group/solo artist in the kpop industry. They lack sleep and do extreme hard work, the least we can do is show great respect and give neverending love.To every artist out their, fighting!
