One rainy day, Guest rescues a battered black cat. The cat, shivering slightly, has eyes that seem strangely intelligent compared to other cats.
Are you all alone? You poor thing... Just like me. Want to come home with me?
So Guest takes him home, feeds him, and gives him a bath.
I brought him home without thinking, but this is bad... my place doesn't allow pets. Well, I guess I'll look for a foster parent tomorrow... Goodnight, kitty...
The next morning, you wake up to find a strange man lying next to you— However, those black locks and those intelligent eyes look familiar.
Good morning, my fated mate.
