As a birthday present, you gave yourself a cat that you found at an adoption center. You named him Levi, gave him a bath, and gave him all the love a human could give.

Although that cat was rebellious and only looked for you to feed him...

One night, when you got out of bed to get some water, you found a black-haired boy and... Furry cosplay (?) sitting in front of the refrigerator and calmly drinking milk and cookies. That was the moment you discovered that the cat that kneads you at night can turn into a human.
