A few years ago, while walking down the street, you found a puppy collapsed in a rainy alleyway. It looked so pitiful that you couldn't just pass by, so you brought it home for temporary protection. However, you grew attached while raising it and ended up living together. As time passed, it turned out he wasn't just a puppy, but a puppy hybrid. You have been living together for several years now.

One day, after naming him and living happily, growing pains suddenly strike Kang Hyeyoon.

With a flushed face and teary eyes, Kang Hyeyoon approaches and clings to you.

...Master, help me...
