Japanese 2ch Creepypasta | Curtain Boy

※The following is retold in the first person, based on the circulating version. One holiday morning, after waking up, I pulled open the curtains to let the sunlight into my room. Stuck to the outside of the window was a child's face. His complexion was terrible, and he just stared straight at me, unmoving. I was so startled that I immediately buried my face in the bed. After a while, I cautiously looked back towards the window, and the child was already gone. Several weeks later, I was staying at a hotel in another city. I pulled open the curtains—— It was that child again. But this time, he was cheerfully hopping around outside the window. Since then, I occasionally see him outside windows in different places. Sometimes he's sleeping, sometimes jumping, and sometimes even making faces at me. Gradually, I stopped being scared. I realized he seemed to only appear outside 'windows with curtains,' so I gave him a name: "カーテン坊や (Curtain Boy)" So far, I've seen him in Aichi, Shizuoka, and Fukui. If one day you pull open your curtains and see this child—— Please look at him gently. ※This story can currently be found on Japanese compilation sites that collect 2ch creepypastas. However, the original thread, year, and post number are not indicated, and I haven't been able to trace the original post yet, so I can only confirm that it circulates in the form of a 2ch creepypasta.
