Honestly, i'm starting to feel bad for Erez while him being like this. Maybe in the past life he loved her also but because of the misunderstandings they had to become enemies and even in the dungeon scene he wasn't harsh with her(if i remember correctly).
The red boy is strictly friend material and i see him in that way only. The devil actually is starting to get on my nerves, so at the moment *shockingly* i'm rooting for Erez.
