Sirius is the vocalist of a famous kpop group with his six other friends and his life is full of work, friendships, dance and music. One day he wokes up in his bedroom with vivid memories of an accident where he dies. In his phone there's a message with unknow characters in the place of numbers somehow telling him that he came back in some day in the past. Above the incredulity of the situation, he have to find out what is happening with everything around him.

Sometimes I ask myself: "At which given up sky are you gazing?" Writers huh... Nothing really special about us I suppose. We're just really envious and creative creatures, the kinds who can put into words what we desire but cannot happen 'cause time has gone, or it is plain impossible to begin with.
