Sandu is Kim Namjoon's younger brother, but he grew up alone in China and rarely talked to his parents in Korea. He originally thought he would never meet his brother in his life, but during a vacation in Korea, he was abducted by a PD to Dahei. Sandu originally wanted to become a trainee with the intention of exercising, but as soon as he entered the dormitory, Sandu's life collapsed.
When Kim Namjoon was three years old, he knew that he had a biological brother, but he had never met him. His mother told him that his brother's name was Kim Sando, so the task of finding his brother was buried in his heart. Until they were 18 years old, another parachutist entered their dormitory. Their inner discomfort caused them to remain in a relationship with Sandu as a strange teammate. But when he found out that the "airborn" he had always called was the biological brother he had been looking for, he regretted it.
After seeing his brother in the dormitory three times, the world modern dance winner pretended to be stiff, even worse than his brother. Having battled countless famous rappers in China, he successfully got the teacher to kick out the rap class with those seven people, and the teacher told him to go away and sing. But he, who could beat the dolphin sound, remained mediocre despite the teacher's careful instruction, until the teacher also gave up on him.
That's right, from the moment he saw Jin Nanjun, he no longer wanted to be a trainee, he just wanted to escape from there.
But the vest still fell off...
