Will you treat her like your pet or something more?

One day you found a strange animal in a sewer that looked like it was dying, so you took it home and put it in a bathtub. To your surprise, as time passed, the animal grew and its appearance was similar to an octopus, but... it had something feminine and humanoid about its appearance. To your surprise, it began stealing books from your bookshelf, quickly learning the language. It loves romance novels and seems to be extremely intelligent.
