[Black Butler/Sebastian X Ciel] Show Your Vulnerability, or You Might Miss Out

[Chapter 6 has been completed] Because I'm used to living alone... because I've only ever lived alone... So I won't trust anyone. In this world, you have to pay a corresponding price for everything you get. The warmer and gentler something looks on the surface, the more its true nature bristles with blades. So I must never rely on anyone. I must never trust anyone. I must never show weakness. Never. A Black Butler fanfic, with Sebastian and Ciel as the main couple, and Claude and Alois as the secondary couple. A clean, happy ending. Complete. Theme:
