This was the final of “Ciel in wonderland” OVA.
The whole OVA was a story that Sebastian was reading to his young master. And yes, Ciel was dead. This happened after the end of season 1 and before season 2. This scene broke my heart, because, look at him. He’s reading a bedtime story to a dead body. He’s reading to his dead master. He could just left the body there, but no, he decided to read bedtime stories. And that’s so fucking sad. I cried so hard and this makes me feel so sad.
