Han Yu-sung embarked on his journey to stardom from the Korean Peninsula, and began to make an impact on the Korean Peninsula music scene and the Western music scene in 2012. He began to dominate K-pop in 2015, and in 2016, the Korean Peninsula officially entered the Han Yu-sung era. Han Yu-sung was lost in the entertainment industry and no one came to his rescue, or perhaps he did not fall into the entertainment industry at all but was afraid to face reality.
