" I picked up a puppy, but it turned out it's not just a puppy."
What if the puppy you picked up off the street turned out to actually be a man, one with an amazing face and physique? Jion accidentally became the savior of one puppy but the next day, the puppy was nowhere to be found, with a tall man lying next to her instead.
Then accidentally kissing turns him back into a puppy, and then back into a man. A confusing cohabitation between her and the world's cutest puppy and at the same time, the world's sexiest man begins.
