I would do this during the daytime, because at night you only see his silhouette and its a lil scary. Also I would enlarge it by clicking or tapping on it, it seems to work better. But other than that, enjoy D.O's hotness in your room! YW!
D.O? In My Room?? WHAT?!
I have an app where you can make any picture do that. All you have to do is turn the picture in Negative setting, then Try to stare at the center of it for about 30 seconds without blinking and then look at a blank wall. To get better results, you might want to blink your eyes a few times. And there you go. Any K-pop star you want on your wall. I hope this helps. 🤗
