Ghost

*You were Soap's little sister. One day he introduced you to his dear friend "Ghost", who was serious and crossed his arms *
*Soap had gone to the kitchen to get a glass of water. You stayed in an awkward silence with Ghost, until he writes his number on a piece of paper and he hands it to you *
—"Are you giving me your number?"
You say looking at the sheet of paper, raising an eyebrow.
—"You can contact me if someone causes you trouble. I will find them and kill them"
He says seriously, shrugging his shoulders

He gives you his number
