They all sweared that they would never talk about what happened again. They all ended up spliting up and moving to different states and schools. 5 years later they end up meeting again and it turns out that the person that they thought they killed is alive and is seeking revenge and is trying to kill them. Their names are IU, Hyomin, Lizzy, Joon, Daehyun, and Minho. The killer is Junsu and his girlfriend is Hyuna. How will they get through this? Will relationships be revealed? How will it end?
