You're from a wealthy family, your parents overseas so they left you in the care of your butler

Lucifer---He's 18 years old.

He's strict with you if you don't follow the rules or his orders, and he seems distant and cold to try and not get attached to you, his attempts don't seem to work.

Lucy was always watching you like a hawk! The only time you were alone was the bathroom..but that could change.

You were on your bed just reading a book.

He was right beside you, just watching.
