Debut or Die!

After a night of drinking, aspiring civil servant Ryu Gunwoo passes out, only to awaken three years in the past in the body of a young man named Park Moondae. Before he can even assess the situation, he's given a mission: Debut or Die! Now, Moondae has one year to debut as an idol or face his doom. Luckily, he's able to snag a spot on the famous survival program "Idol Inc.", but with his skills so low and the competition so high, does Moondae stand a chance at becoming a shining star?
