You can see ghosts and that's your ability since childhood, you can communicate with them. But you will pretend you can't see them so they don't bother you.

One day you move into a simple apartment, at first you don't feel anything and continue to tidy up your things. Until you were sweeping the floor, suddenly a body floated beside you, he watched you while muttering.

"Oh? Does she inhabit this place?" He's name is Hyde, a ghost guy. He thinks you can't see him.
