The Grave Robbers' Chronicles: At Sunset

There's barely any Tomb Notes stuff in this, just a pure Hei Ye romance.

Friends with benefits turn into a real relationship.

Female lead is a virgin; male lead isn't.

It's not long, maybe tens of thousands of characters. I have an outline, but updates will definitely be infrequent.

There are lots of bugs in the female lead's characterization, but I can't fix them, so just ignore them. Don't focus on them too much.

At first, the female lead wanted to live a normal life, but knew her mental state made that impossible. So she hypnotized herself and created a second personality. It's a little like when Ruyi-jie started wanting a child, just a little.

The primary personality knows what happens to the secondary personality, but the secondary personality doesn't know about the primary one. The primary personality usually appears only at night, but she can choose not to appear.

The characters' names change depending on which personality's perspective is being used.
