When Sehun and Tao experienced the unexpected yet unbelievable thing in their life after that 'failed' ritual.

"You must be joking, right? Awhile ago you were the one who said that ghost won't haunt us because we simply couldn't see them though because we haven't that 'gift' to see them"

 " it Tao, I'm not ing kidding, I swear I'd ing throw my body out of window if its just a joke"

You call them, they'll come.
