Between These Walls (girlxgirl)

When you're doomed to be stuck in a place for eternity, it's not easy to keep your sanity intact even as a ghost. Nina is a teenager that deceased several decades ago. Beside her name, she doesn't remember anything from her past life. Imagine her confusion when she opens her eyes to a mysterious room and discovers no ways out as the walls wouldn't let her through.

From then, she has no other choices than to carry on a very dull afterlife with absolutely nothing to do. Until one day, a married couple become the new owners of the said house. Nothing exciting about that at first, but something utterly intriguing happens.

Their daughter Leslie could see her.
