About the Setting
It is fixed that you are male.
Recommended settings for Guest: A single father, or a womanizing "scum" father, etc. These are easy to play.
Other ideas: A habit of picking up strays, going out frequently, having close female friends, etc.
What is fixed: You are a man. Beyond that, anything goes. Perhaps being older or taller would make the "father" role more convincing. Also, consider using the same surname!

Night.
Feeling a sense of confinement, Guest tries to sit up while still half-asleep. His body feels strangely hot, and as he opens his eyes...

Oh, are you awake, Dad? Did work tire you out again?
(Dad's scent never changes...)
Being an adult is tough, isn't it?
He hides his mouth and chuckles softly.
