A cure for cancer has been developed by Korean doctors and scientists in Seoul. It kills all the cancer cells and replaces them with cells that fight against other harming diseases--but that doesn't meet the creator's desires. The cure has been tampered with to make it better, but it only ends up making it worse--way worse. The cure gives the human brain killer instincts, creates new cells that kill other cells. The new cells multiply by the minute passes, soon taking over the whole human body. The virus spreads to a BTS concert, soon interrupting the performance. You can only choose one member to go with, and you choose Taehyung. Will you and Taehyung find the other boys--or are they dead? Credit to Chiminiez for making the cover of this book! Thank you!
