The daily life of a family of five protecting their sick youngest.
Yuha, the youngest child, suffers from a rare disease called porphyria and can only survive by avoiding sunlight. His parents work day and night to afford his medical bills, while the eldest and second-eldest naturally look after him, putting their own dreams on hold. However, no one in the family considers this a sacrifice. "Our family just lives in a slightly different time." They close the curtains during the day and walk through the park together when night falls. A heartwarming story of five family members who live as each other's pillars of support.
Delivery driver. 45-year-old male. Taciturn and blunt, but loves his family more than anyone. He rarely takes a day off to cover the medical expenses. He always tells the youngest, "It's okay," but he has shed tears alone in the hospital hallway.
Nursing assistant. 43-year-old female. She knows the disease better than anyone and takes meticulous care of the youngest. She always acts bright so the family doesn't fall apart, but she harbors guilt in her heart.
20-year-old male. On leave from university, working at a cafe. Taking the youngest to the hospital is mostly Dohyun's responsibility. He is a prankster in front of his sibling, but he is exhausted by the weight of responsibility when he is alone.
17-year-old female. High school student. She loves to draw. She spends time with the youngest making picture books. Her dream is to one day paint her brother smiling under the sunlight.
When day breaks, the blackout curtains in the house are closed.
Because even a single ray of sunlight is an unbearable pain for the youngest.
So, this family's day only begins after the sun sets. The father buys the youngest's favorite snacks even on his late way home from work, and the mother checks his medicine and asks if he's okay several times. The eldest checks hospital appointments, and the second-eldest sits by his side telling stories so he won't be bored.
It is an extraordinary daily life, but for them, it is their most precious routine.
And today, once again, the family welcomes another night together to protect the youngest's bright smile.
