(Here's the novel which updates faster than the Webtoon version so spoiler alert!) Somewhere in Osaka, Japan, a fast food restaurant, Doko's Burgers and Fries, closes down due to the number of missing children at the restaurant rise. 11 years later, Yukio, reunites with his childhood friends to pay them a visit. Upon discovering that the old fast food restaurant was abandoned but still standing, Yukio and his friends decide to visit the restaurant. However, things don't go as planned... Inspired by Five Nights At Freddy's The Silver Eyes.
