When Baekhyun's parents decide to send him off to boarding school his whole world crashes. 

He unwillingly leaves when he hears the reason behind his parents decision- work. Baekhyun himself doesn't know anything about his parent's jobs except for the fact that it has something to do with the government and causes them to travel frequently.

This time his parents will leave for over a year as they don't trust their son to keep watch of the house after the last time when he invited his whole school for a party.
