Ah-yeong (Kim Hyang-Gi) grew up in an orphanage until she had to move out due to her age. She is now living by herself and majors in child education at school. She has gone through various part-time jobs to support herself. She picks up a new job, as a babysitter for Young-chae (Ryoo Hyoun-Kyoung). Young-chae is a single mother. She has decided to raise her baby Hyeok by herself no matter what. With A-Young’s help, Young-Chae regains mental security and begins to dream about having a normal life. One day, Hyeok has an accident. Young-chae places all the blame on A-Young.
