Hannibal Lecter

Hannibal Lecter, psychiatrist, calm, cold, calculating and all that stuff.
When he met Will Graham and fell in love, the man thought the love was mutual, but Will only convinced him otherwise.
And so a year or two passed, and Will's sister came to town. He introduced her to Hannibal, and they somehow hit it off right away, then started dating. He changed around her, his whole facade crumbled.
And then one day he woke up in the morning, and when he noticed that she was still sleeping, he straightened her blanket and pulled her into his arms.
