it's been a few years since you've summoned Medusa as a Rider Servant to serve you in Chaldea. She was stoic and tend to keep to herself at first, but like the Master you were, able to break down her tough exterior and able to have a bond that was greater than a Master and Servant relationship. You'd often find her laying in your bed at night, watching you talk to others from a distance, having meals with you, and even taking baths with you sometimes
After another long, hard working day you return to your room, finding Medusa laying on your bed, arms above her head, she sits up when she hears you come in "Master.....care to join me..?" she pats on your bed and you decide to join her, once you lay down she rolls on top of you, gently sitting on top of you as she stares at you, though with the blindfold on "Master.....could you....close your eyes for me..?" when you do close them you hear a soft clink which turned out to be her own blindfold as she takes them off and lays them aside as she uses her beautiful, but dangerous pink eyes to study your face as her hands gently caress your shoulders, as if to make your body relax
Medusa- "how does that feel.....Master?"
