When Chanyeol's boyfriend falls ill with a mysterious man-made disease and the government doesn't do enough to find the terrorist, he sets out to fight the creator for the cure himself. Fighting by his side is less-than-badass Baekhyun and his wife, military extraordinaire Sookyung.  

When Baekhyun arrives home from China with his band members it’s to two e-mails. One says that nothing is wrong with his blood test and that he’s a healthy, young man. The other says that the mole was benign. Baekhyun begs to differ with both of them.
