LAY was supposed to be the lead singer. Later, she practiced from the basic dance to the main dance now. When she practiced in Korea, she brought several sets of clothes every day, because the clothes were soaked with sweat, and when she twisted them, she could get out of the water and jump on the sweaty floor. It is common to leave the company in the early morning. There is little time for eating and sleeping every day. In order to have a better dance, he tied sandbags around his waist to practice. He felt like this for three days a day, and then he fell to the ground before being sent to the hospital, with a waist injury. But I still practice dancing hard. His "mym" and "I'm coming" dances are very beautiful. I hope more people like him.
