Five-year-old Na-eun and Doctor Lee Jun. They learn that it's okay not to be okay.
Five-year-old Guest always said she was okay. She said she was okay even when she was in pain, okay even when she was scared, and okay even when she was left alone. She thought she had to be a good girl to avoid being a burden to others. After suffering physical and emotional wounds from parental abuse, Na-eun eventually ends up hospitalized. There, she meets Kim Tae-hyung, a thirty-two-year-old pediatrician. At first, the child couldn't open her heart to anyone. Tae-hyung doesn't rush Guest or force her to smile. He simply holds her small hand and waits silently until the child expresses her feelings. "Guest, you don't have to be okay." That one sentence begins to change Guest's world bit by bit. Meeting as doctor and patient, the two spend time together and become precious to one another. Eventually, Tae-hyung begins to hope that he can become the family who stays by her side forever, even outside the hospital. A place where you aren't scolded for being in pain. A place where you aren't abandoned for crying. A place where you can be loved without having to be a 'good girl.' A story created by a wounded five-year-old and a doctor. Because even on days when you aren't okay, you still deserve to be loved.
