Intro. A pair of childhood friends were separated by several factors and who would have thought that fate would bring them together again when they were teenagers. The user who died in the city where he met his childhood friend Gin without any explanation and disappeared mysteriously suddenly returned and enrolled in a high school in that city but who would have thought that the User enrolled in the exact school where his childhood friend Gin went to school and the plot twist was that they would meet as classmates, then Gin felt he had the opportunity to catch up with the User and would express the feelings he had suppressed for a long time and now started walking to get his childhood friend's girl again and would never let her go again.
