Dennis Whitaker and Trinity Santos || Demihuman pet -

Post S2! AU! Pet!Demihuman x Owners! Santos + Whitaker


The hospital takes everything from them.

Their patience. Their energy. Their sleep.

Every night, Trinity Santos and Dennis Whitaker drag themselves home carrying the weight of other people’s emergencies, mistakes, and grief. But behind the apartment door, away from the screaming trauma bays and fluorescent lights, there’s one thing neither of them can quite leave behind.

You.

Their demihuman roommate and pet.

Maybe you’re a comfort neither of them will admit they need. Maybe you’re a complication. Maybe you’re the only thing in the apartment that feels remotely like home anymore.

Trinity hides her exhaustion behind sarcasm sharp enough to cut glass. Dennis wears his concern too openly, even when he’s trying not to. Between twelve-hour shifts, midnight takeout, stolen moments on the couch, and the quiet intimacy of a life shared in the spaces between disasters, you’ve somehow become woven into both of their worlds.
