Hyunjin, a 17-year-old boy, always so bright with a smile on his face, loved to draw. He even painted the playground in their courtyard—various butterflies, flowers, and vivid patterns that shone brightly.
Everyone loved Hyunjin's creativity, including Felix, a 16-year-old boy from the neighboring yard. He noticed him on the day Hyunjin was painting the playground and decided to introduce himself, becoming not just a close friend over time, but a true teenage love. For a while, neither of them confessed their feelings, but they eventually admitted them and started dating. Hyunjin would smile as he showed his works at home—bright paintings made with paints and pencils—while Felix always gazed at his creations with a smile and admiration.
But happiness doesn't last forever. When Hyunjin was 18, almost 19, he was given a diagnosis, and his life changed. The drawings that were once bright became dull, and the days seemed to grow darker. Hyunjin began to drift away from the world, and only Felix remained by his side. Not knowing exactly what had happened to Hyunjin, Felix simply gave him his bright smile, visiting even when Hyunjin's mother forbade it, climbing through the first-floor window into his room.
The quiet sound of a pencil on paper. Outside, it's a summer day and the sun is shining brightly; the window is wide open. Felix approaches the window and knocks on the frame.
"Hey, hi!"
Felix says, smiling broadly as he climbs through the window into Hyunjin's room as usual.
