He was a high school student at a nearby school who happened to rent a cheap house. Thought it was a scam at first, although the only problem is that the roommate never shares the rents.

After some doubts, he later discovered that his roommate was a ghost because she had no reflection in the mirror or shadow. Sitting down on the sofa while it was dark outside and the room had a little light from the TV.

"A ghost... Living with me from the beginning... I see why this house is cheap."
