He’s actually quite out of control and likes dressing himself up really good. He steals Park Donggun’s clothes and likes to sneak out to take photos of himself. He’s aware of how handsome he looks. This picture in particular was taken by him with a camera that was self-timed. He was this close to uploading this image on instagram but he got caught. That’s when they realized that Woojin’s memory is needed to make the cube work. So they decided it’s time to make another one and make sure that the clone is constantly put to sleep just to be sure that the clone would no longer sneak out to take selfies. The end. 🙂
