I refer to Grelle as a female in these scenarios hence why the title is Boyfriend/Girlfriend Scenarios not just boyfriend.

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^^

This is a reader insert for Black Butler. It is set in London, 2018 when (your name) (last name) finds a box of oddly coloured kittens. But she takes them in anyway! Because who doesn't love kittens?! (If you don't, shame on you) I'm terrible at story descriptions...

Her older brother dies right before her eyes. The flames are licking their bodies. She isn't bothered, but his body is quickly burnt to ashes. She screams in agony, tightly holding her burning brother in her arms, as the thick, black smoke is filling the mansion. The smoke fills her lungs and as she's feeling her consciousness slipping away she's saying a prayer. Not to God, not to Satan, nor to the angels or the demons, but to the Reapers. "Please spare my brother's soul."

This was a one shot that became a story
