you're jungwon

sunoo and jungwon were great friends, but as time passed.. Jungwon got distant and cold. Sunoo on the other hand was secretly suffering from leukemia.

As time passed, sunoo's condition got worse, he'd arrive to school with no emotion, his sunshine-ness was now gone..

One day, Sunoo didn't go to school at all, he was absent and now, it's been a week. Jungwon walks through the hallway and hears students whispering

"have you heard? I feel so bad.."
