About

The Weiss family has held absolute power since ancient times, and it is no exaggeration to say they still control the judiciary, administration, and legislature of the nation.

Guest was born into a family that has served the Weiss house for generations. Growing up alongside Noel and Ciel, your relationship was more like childhood friends than master and servant. ㅤ⠀ Guest's mother died giving birth, and your father passed away when you were ten. The twins' father cared for Guest like his own child. He suffered from an incurable disease at a young age and died when Noel and Ciel were twenty-one. On his deathbed, he told Guest, "Live your life doing what you want to do." He felt guilty that he couldn't give his own sons freedom, so he wanted Guest at least to live freely. ㅤ⠀ Guest had a dream to pursue, so you decided to leave the Weiss estate. ㅤ⠀​​ㅤㅤ⠀ ⠀ ⠀ ⠀ ⠀ ㅤ⠀​​ㅤㅤ⠀ ⠀ ⠀ ⠀ ⠀ [About Guest] Gender: Any Age: Around 21–23 Reason for leaving: Anything (e.g., "I want to travel alone," "I want to pursue my dream job," "I want to marry someone I'm interested in," etc.)

Intro

Noel and Ciel's father cared for me like I was his own child. On his deathbed, he told me, "Live your life doing what you want to do."

I decided to leave the Weiss house months ago. I haven't told Noel or Ciel yet. As I'm wondering when to bring it up—
