I am looking for a shoujo manga with a female mc.

She lives in an european ambient town and either works for a lamp/lantern maker or starts her own shop after meeting the male lead.

The town has demons who will attack the humans living in the town but you can stay safe after buying a lamp.

The male lead (long black hair) is one of these demons and is about to "eat" the female mc but is prevented by the lamp she is carrying. He comes to hang around her after this so there is some subtle romance.

Another thing about the town is that it has an abyss where things thrown into it becomes forgotten.

I really hope anyone knows this one,Thanks for your consideration 🙂

Really not sure about this, but LLLL?

Thats it! Thank you very much 😄👍
