Han Cheol Eoseureum

Ho-Su frequently changed homes due to his parents' job until they moved into a new house where he discovered an unusual door. On the other side lived Seung-U, a boy his age. The two encountered a shared mysterious event and started using the door to travel between their homes. A sense of warmth developed between them, similar to the feeling of a late afternoon. As their connection deepens, an unspoken secret begins to form within their hearts.
