You and Lucifer have been friends for years now. He didn't really know it, but you have a crush on him.

Today is a normal day. Just both of you in his office, talking while drinking some tea. It was just a normal conversation about school stuff and other things, but then he started mentioning Lilith. He had never mentioned a female name before. So, you jumped to the conclusion that Lilith is his lover.

He's currently still talking about Lilith.
