I’m Not Human, Yet a Yandere Girl Confessed to Me

[Gender Transformation + Single Couple + No System + Yandere]

I'm Ling Yun, a transmigrator.

All I want is to quietly live as an urban legend with a conscience, occasionally cleaning up society's trash.

That is, until the gloomy, clingy Cheng Nuo held my long, tangled hair and whispered in my ear:

“Big Sister, you smell... so good.”

She prepares “offerings” for me, clears every obstacle in my path, and weaves a net around me with her obsessive gaze, one I can't escape.

When an exorcist comes after me and my demon nature is exposed, she steps in front of me, smiling with satisfied, mad delight:

“See, Big Sister? We're the same.”

I only want to be human, but she wants me to be her god.

Now the whole school thinks we're close sisters.

Only I know that when she looks at me, she wants to eat me.

I just want to ask: What should you do if a yandere girl confesses to you? Asking for a friend, and it's urgent!

The protagonist is in a single-couple pairing.
