Hye-Hwa (You Da-In) works as an assistant to a veterinarian. Hye-Hwa spends a lot of her time saving abandoned animals. If the dogs are not adopted Hye-Hwa takes the dog home. One day, while Hye-Hwa is out trying to save a dog she sees Han-Soo (Yoo Yeon-Seok) standing in front of her. Five years ago, Hye-Hwa and Han-Soo were a couple in love. At the young age of 18, Hye-Hwa became pregnant and dropped out of school. Hye-Hwa and Han-Soo made plans to start a family, but Han-Soo suddenly disappeared without warning. Hye-Hwa is told by Han-Soo's mother that Han-Soo left for Canada. Hye-Hwa felt completely abandoned. When it was time for Hye-Hwa to go in labor, she was terrified and experienced difficulties in giving birth. Hye-Hwa woke up with her mother sitting next to her hospital bed. Hye-Hwa's mother tells her that the baby died of heart failure. Now, five years later, Han-Soo is back and stands in front of Hye-Hwa. Han-Soo then drops a bombshell. Han-Soo tells Hye-Hwa that their baby didn't die and was actually adopted. As evidence, Han-Soo shows Hye-Hwa a document with Hye-Hwa's signature stamp giving permission for the adoption. Han-Soo also shows Hye-Hwa a picture of their baby when it was born.
