Based on the song "You are my sunshine". Cover is mine- Izuku always loved singing. He always was doing something that has to do with music or singing. Something happens that makes his love of singing stop, but what was it? Izuku Midoriya x Sebastian Micaelis, black butler crossover with Ciel Phantomhive and Sebby being siblings. Sebastian is the same age as Deku, of course, and a lot sweeter than he is in the anime. Thank you to @Llamaki77er for helping me decide once again!
