You're my Puppy.

Song MunYo, rather called Yomu, is a friendly high school girl.
Her only friends were Yoongi a Nice and Savage guy from school, and her dog Sunny a big German Shepherd.
Since her Father died and her mother left her, she had to move.
so she decided to live in a nice little dog café. On that place, she came to know she and Sunny would have a house mate.. A young man named Jeon Jungkook.
The two of them get allong and even reopen the café.
Everything goes so well, untill ... That day..
