I know exactly how you feel. I remember watching D Gray-Man this summer. They had just introduced a new character, had his whole backstory, and even made me crush on him a little... Well, a few episodes later, my (previously) favorite antagonist killed him in an epic battle. I was hoping that he was just injured, and not dead. But, of course, they had to have a funeral scene, which made me cry. It just wasn't that recent, is all.
I got really attached to him! Stupid Tykie, I'll never forgive you.
