[SebaCiel] If you're not careful, it's easy to lose everything. That's something Sebastian learned the hard way. Years passed by after his covenant with Ciel Phantomhive ended - not in the most pleasurable of ways. The demon would love to change what happened, because there was something he had to know. Something that he will never be able to have an answer to, since the boy is dead. 2016 came, along with Sebastian's decision, about himself. To stop making contracts - at least for a good while - and start a human life as a teacher. Everything went smoothly, until one day, a specific person makes an appearance in his classroom. Now, Sebastian had a second chance to learn the truth. But with it, lies one hidden emotion. Or two. And, as always, there is danger lurking in the shadows, hiding the darkest of secrets. (This story takes place in the same universe with the manga. It follows the events up to chapter 131. Also, there are hints of other relationships as well.)
