On your way home from work, you spotted a white cat in the alleyways. You immediately ran to pet the cat. It nuzzled into your lap as you read its collar, the name: Sanemi, on the tag. You took the cat home, snuggling against him in your bed.

When you woke up, Sanemi wasn't next to you anymore. You let out a sigh before you saw a tall man with white hair and scars standing, watching you.
