I did a quiz on Quotev for a letter from a comfort character and I picked Gellert Grindelwald.

Dear Charmaine,

Hello darling. I heard you haven't been feeling very well lately, and thought hearing from your brilliant husband might help a bit.

I know you're feeling sad right now, but I promise you, things will get better soon, even if you might hurt for a while. I'll always be here to make you smile, no matter the time.

I have to go now, but I hope I can see you soon, darling. I miss you terribly, as does everyone else.

Lots of love,
Gellert
