A Beautiful Tragedy

(Yandere various Black Butler x male reader) You have been living in Germany for years yet you want to leave this country. You couldn't, because they are watching you and they will go after anyone you care about to make you suffer. It is all because you're an illegitimate child, holding a power that has been your curse since the day you were born. And you have too many reasons to distant yourself from others so they won't get hurt.

Until one day you received a letter from your younger distant half-cousin. He found a solution for you to leave and helped you. You were grateful for him and in exchange for his help, you will help him too along with his demon butler.
