Aru has a habit of cracking his knuckles
every single one of them, even fingers and toes
then he cracks his neck
five times a day
this habit of his annoys Eru very much because he can't stand the sound
bonus:
Aru once tried to crack Eru's knuckles when he wasn't paying attention and even today he still holds a grudgemainly because Eru let out a weird sound while the others were present so ¯\_(ツ)_/¯
