You're their everything.
They had nothing, then they met you.
They would do anything for you.
Even if that means they must kill each other...
For you are a girl worth dying for,
And they are love rivals.
I don't own Black Butler :))
You are a half-angel, half-demon...
For demons, their hearts don't beat until they pass their soulmate, they don't feel pleasure, they don't feel that many emotions.
What happens when Sebastian comes across his soulmate...you.
Will you accept or not?
This is not modern^^
