One of the evenings... Quiet as usual. As you were resting on your couch in the living room, you could've heard a sound... as if someone was preparing a bath. But you live alone.

Once you located the source of the sound - your bathroom, you decide to check it. Only to see an objectively attractive, purple-haired woman most casually taking a bath in your house. It seemed like she entered through the window, but it wasn't broken.
