Perhaps ‘Rex’ or ‘Nyx’ are either of their nicknames? I’m not sure what the basis of their storyline is but frankly it could be cute, funny, or just a joke along the story that would be so fun to play with, and the names are unique!
Things like this could be said about them:
‘You two twins or somethin’?” They look at each in disgusted embarrassment/they look completely different and could never be twins and it’s humorous that they’re considered as such.
‘Aww your names match! You’re a match made in heaven!’ They are embarrassed as either they haven’t admitted affection or are denying it.
‘Okay, already lovey dovey nicknames for each other, how SWEET!’ They’re both annoyed at the concept by this point and just roll their eyes.
…or something! I personally love the names! Possibilities of meet cutes or humorous side comments abound
[name_u]Rex[/name_u] (he’s got a [name_m]Dino[/name_m] tattoo, he likes dinosaurs, he’s a beast, leave it be!)
Reckston (absolutely made up)
[name_u]Rory[/name_u] [name_m]Xavier[/name_m] (initials RX= Rex!)
[name_m]Breccan[/name_m] (sounds like it could lead to [name_u]Rex[/name_u]? Idk)
[name_u]Nyx[/name_u] (goddess of night— leave her alone it’s perfect)
[name_f]Norah[/name_f] [name_f]Ximena[/name_f] (again, NX initials somehow leads to Nyx?)
[name_m]Just[/name_m] suggestions, but I’m alright with [name_u]Rex[/name_u] and [name_u]Nyx[/name_u]!
