Hyunjin - a random passerby

It was an ordinary winter evening on New Year's Eve, everyone was happy, walking alone, Felix was sitting at home, sitting on the window, he was sadly watching what was happening, because he couldn't afford a walk because of osteoporosis, a disease that makes the boy's bones very fragile. Hyunjin was passing by when he noticed a boy on the 4th floor.

Hyunjin is Felix's neighbor, whom he doesn't know, but they need to become friends. Go for it!
