OCs will be referred to as OC 1 and OC 2, and same with Crushes to make it less confusing.
OC 2 = MY OC
OC 1 = Your OC
(Cna be switched around if you so wish)
OC 1 is walking around when they hear someone planning to kill OC 2, but can't tell who's planning it. Worried and frightened, they rush to OC 2 and tell them. The pair agree to stick together. Crush 1 and Crush 2 overhear the exchange and decide to stick with the pair as well to protect OC 2.
