This flash mob was organized with the aim of cheering on the youth so that they can stand confident in a society through revitalizing their love for and expectation toward life, and as a way to diminish their despair and distress regarding their future job prospects. 

The flash mob aims to construct a more positive environment in which citizens can relieve their stress, depression, anxiety disorders, and other mental disabilities through their interactions with various celebrities and artists, and to ultimately serve as a preventive measure for suicide.
