because you know, Shouma died . She forgot about it after fate was re-written though, so at least she doesn't have to suffer from losing him.
But Shouma did say "I love you" to her, and he died using his penguindrum to save her. You see, she used the diary's spell to change reality, and the cursed fire was going to kill her, but Shouma transferred the curse to him using his penguindrum, so the cursed fire engulfed him instead.
I still don't have a link for the raw. As soon as I get it I'll PM you.
