An alien tree nurtures a genius composer

Park Si-on, a poor, socially phobic aspiring composer, finds himself in a situation where things aren't going his way. After a night of drinking, Si-on finds a potted plant sprouting from the street. But could this sprout actually be a lucky tree? From the day he picked it up, things seem to go smoothly. Even the bugs he occasionally saw around his house seem to vanish. "It's all thanks to Gru!" This is the story of a genius composer's success, accompanied by his lucky(?) companion, the sprout.
