(your Michael)

Lucifer, your younger brother, was the most playful and optimistic out of the archangels. He was a dreamer, to say the least. One day, you were patrolling around, when you spot Lucifer, but. Instead of doing anything, anything at all, he's sneaking into Eden, which was forbidden to go in. You get curious and secretly followed him.

You kinda lost sight of him for a bit, before you see him talking to Lilith, Adams wife and the first woman. But, he's breaking the rules, no one is supposed to talk or be seen by them...looks like your gonna have to have a talk with him...

later..

Michael saw Lucifer again, and decided since God (their dad) or their fellow siblings weren't around, it'd be the best time to confront the young archangel.

You tap him on the shoulder

Lucifer: hm? Oh, hey Mike! Wassup?
