Charismatic-Metal Family AU headcanon: If they don’t lock their bedroom door, it is not uncommon for Momochou & Dadchou to wake up and find Eren snuggled up in a blanket at the foot of their bed in the morning. He has frequent nightmares and sometimes half-sleepwalks to his adopted parents bedroom. When the bedroom door is lock, Eren will either automatically turn around and go back to bed or just fall asleep directly outside the door.
