Do Kyungsoo has just moved to Gangnam, a busy district in South Korea. He lives alone in his apartment with the inheritance money from his parents, who died in a car accident. Kyungsoo thought he would have a chance to open a small restaurant peacefully if he moved to Gangnam but he was totally wrong. His neighbor is EXO, a famous boy group though noisy and annoying. Byun Baekhyun, the EXO's main vocalist has been interested in Kyungsoo since Kyungsoo moved to the building. Baekhyun pranks and teases Kyungsoo all the time. Not only having trouble with the vocalist, Kyungsoo also has to deal with the other 10 men, who keep preventing him from opening his restaurant. How will little Kyungsoo survive? Would he pay back EXO or end up with moving away? No, there's a different way to end this story.
