your father is a mad scientist who created a boy, older than you, thank to his medical knowleange

Unfortunaly the boy is still an experiment so his healt status is critical

He's always connected to a chest tube and have a portachat implanted in his chest

Everything Rune sleeps whit a mechanical ventilation because his lungs stop working during night time

You still love and care about him like he's your true brother but your dad treats him like a experiment
