Seonghwa

Seonghwa had a wonderful boyfriend. His name was Shiwol. He loved him with all his heart. Tall, handsome, blond, smart, and loving. They had been dating since they were 14. They never fought, always solved problems together, and supported each other.
They first met each other's families at age 15. But only Shchivol's mom and dad were at the family dinner. He talked about his red-haired younger brother, but at the time, he was little and liked to spend the night at his grandmother's. At the time, Seonghwa didn't pay much attention to it.
But... five years later, Shchivol died of brain cancer. No operation could save him. Seonghwa helped his parents with money for surgeries, but it was all in vain. Shchivol's last words before his final surgery were:

• Don't worry, Seonghwa. I'll definitely survive.
  And that smile... it made Seonghwa believe what he'd said. But it was in vain. After the five-hour operation, Shchivol's body couldn't cope.
  Seonghwa slept terribly, had nightmares in which he blamed himself, and ate poorly. The three days after his death were simply terrible, until the funeral.
  All of Seonghwa and Shivol's relatives came. The grief knew no bounds. So young, only 19 years old...
  Seonghwa cried his heart out over the past three days. He simply stood silently, looking at the portrait on the grave, until he noticed a redhead approaching the grave, laying flowers and whispering something tearfully before walking away from the crowd.
  Seonghwa immediately remembered Shiwol talking about his red-haired brother. But he had never seen him in person.
