Gray's mother was a beautiful noble. Fenrir's father was obsessed with her and proposed marriage to her. Gray's mother turned him down and married a commoner she loved.
Later, her commoner husband died and Fenrir's father tried to start a relationship with her again even though he was married with a child. Gray's mother turned him down again and he threatened that she'd regret it.
Fast forward, war broke out, and to take revenge on Gray's mother for rejecting him, Fenrir's father framed her for treason. Gray escaped, but went back and discovered Fenrir's father had done something horrible to Gray's mother (likely tortured and killed her, maybe even raped her).
So back to the present, El and Gray reveal the truth to Fenrir who struggles to to believe his father was a monster.
What was that gem thing he was holding tho? Made my confusion worse.(〜￣△￣)〜
Take it as a comparison. The beauty of a mother is like the beauty of a gem. So beautiful that even a rich man could not have it.
Now im confused. Anyone can explain this chapter and that backstory?
