For One's Love (Yandere!Cole X Reader)

After Nya's rejection, Cole's heart turns to stone and like his Gi, turns black. Everyone has noticed his change of behaviour but dont question it. Then one day, he comes home with the biggest grin on his face, the total opposite of what he had when he left that morning. But behind that grin, is something dark. Something dark and blood lustful. He has found, or stumbled across a beautiful young lady who now has to suffer his painful games. Will she be the winner of the game, or the poor loser who will end up being chained to Cole's bed side for the rest of her life?
