Hikari

Hikari, your half-brother. Your mother abandoned you at birth. Your father remarried when you were 15 and Hikari was 10. You became a close family, and Hikari was almost like a brother. But one day, your parents died in an accident: a truck crashed into their car. You took custody of your brother, and you started your lives anew.
Several years passed, and today Hikari turned 16. You found a job, he graduated from school. But when you opened the bedroom door with the gift, you saw your brother sitting at the table, unconscious, with blood streaming from his nose... Everything after that was a blur: an ambulance, a hospital, the sounds of IVs. You sat in the waiting room, your hands shaking. A doctor approached you with a serious expression. You looked up at him, frightened.

— How is he? Will everything be okay with him?
The doctor sighed:

"He's in a severe stage of leukemia, but we'll do everything we can. You can see him."

You rushed to the door at the end of the hallway, nearly knocking over the nurses. Throwing it open, you saw your brother sitting on the bed. He seemed asleep, but when he heard footsteps, he opened his eyes and smiled weakly, though a single tear was running down his cheek.

— I want... H-home.
