(Mer and Human combo suggestion)
I feel like a deaf human or a blind human would be a great candidate to for this role.
The mer knows of this disability of theirs and takes more responsibility and care over the human (maybe too much care).
If the human is deaf, the mer lets them feel the deep vocalizations they make. Holding them close to their throat or chest to feel the hum or purr they might make, vibrating the little human.
If the human is blind, the mer constantly guides them everywhere they go when theyāre at sea for an odd reason. Always wandering what their eyes look like or used to look like (maybe their eyes faded? š¤·āāļø). And having free will to stare at them all googly eyed, without the human knowing or feeling freaked out by it.
Ooooh both are good! I went with the second option.
The human is chill and fully trusting the mer to gently guide her. ;)
