Yeah, i know it's a bit boring, But i wanted to do a small comic showing how awkward Rei is with acting like a normal kid.
In the Towers the children are alone from the start, Rei has never shared a room with anyone till he met Anei.
After Anei there has always been someone there (like Phico)

This night the grown-ups of the group needed to discuss some things and Anei told Rei to go ahead and sleep...
Then Rei found that he couldn't get to sleep, peeking out the door he was spotted by Yero. He explained his situation and she was more than happy to help and keep him company.
Then this convo happened.

Anei was once nice and quiet 8D
