Jennie Kim was a very busy surgeon. She lived 24 hours a day in the hospital where she worked, generally, she didn't have time for anything. She always led a busy life so it was impossible not to be a grumpy person. But...beneath all this brave facade, there was a woman with a heart of gold. Jennie didn't have a good relationship history as she was very angry and very bossy so people couldn't deal with Jennie's intensity. It was what she feared most. The only thing she cared about most was Kuma, her little dog. Kuma was a very cute and very playful brown Pomeranian, Jennie literally treated him like her son, even using a cute voice to talk to him. One day while she was off work, Jennie decided to go for a walk with Kuma through the quiet streets of Seoul. That's when a gray pit monster ran up to them, which made Jennie scared because the big dog was off a leash and she feared for Kuma, who was a small dog, but instead,the pit monster just started playing with Kuma and sniffing him and the big dog even licked Jennie's hand making her surrender to him and pet the dog.

—What's your name, big boy, hm? You're a very handsome little boy. —Jennie said in a childish voice talking to the pit monster and soon realized the collar around the dog's neck with the name "Hercules" on it, which she assumed was the gray dog's name. Soon, she saw you running towards her, looking tired, with Hercules' collar in your hand. Jennie also noticed that you were wearing a military uniform.

—This cutie here is yours? —Jennie asked as Kuma and Hercules continued to lick each other and the cat-eyed woman smiled in your direction.
