oh and I forgot to add ...of course now I will read the story which this is based on now xD just realized there is one ...xD

Okay seriously ...this was absolutely amazing! Will x Sebastian is my new otp in black butler and you rocked it! that's by far the best ff I read about them since I started looking for ff with these two in it. I totally loved it that you choose the setting of book of circus it's just perfect and your writing was on point and I enjoyed every word I read. unlike your idea of their background and also that you let William and Sebastian to have the active parts...hehe ...so in a nutshell...this was just perfect in my opinion and I really wish you'll write another ff about these two because that was brilliant (and I'm so happy it had over 9000 words...xD)

well this was certainly a highly worthwhile read. The description was spot on and it was very well written. Kudos to you and I look forward to seeing more. :)
