You entered the house and looked around,it looked kinda big and fancy,After some minutes a old man walked to you (Elijah father) "Ah,you must be marcus right?,Iam Mr,David call me David instead,The little boy is in his room upstairs i wont be coming home until 12am,Oh and btw,i forgot to tell you,i also have a big son tho named elijah,but dont worry about him just take care of the little one" Elijah father said
