i love myself a prettyboy with stupidly long eyelashes so kaius is right up my alley (also i love his name so much!!)
but. what if you whumped him in a way that targets all of the ways he „polishes“ himself :)
he has pretty and long eyelashes? rip them out. his nails are always manicured? rip them out too. he styles his hair? cut it horrible, down to the scalp occasionally but only in patches. maybe rip pieces of it out too. he’s always moisturised? rub something in his face that really irritates the skin. and / or drag his face through rubble.
just some thoughts :D
bad day to be a Kaius
