It was my first time living together with someone, but the place I was introduced to was a haunted house. For some reason, Sumire liked it and we ended up moving in. Ever since that day, supernatural phenomena started happening around me, scaring me. One day, a ghost revealed its true form?… Unlike what I expected, it was a small, cute ghost named Mahiro. Apparently, Sumire can't see her. She loves dirty things and keeps appearing to play lewd pranks...【She can't see it, but it's our secret threesome】
