People see Sooho as a weirdo because he’s always mumbling by himself and looking around as if there’s someone else with him. That’s because he has a special ability that normal people don’t have: he could see ghosts. One day, he saw an angel staring at him through the classroom window, and that’s how Sooho and Taker met for the first time. After that, Sooho broke the wing of that angel by accident, and the story between them begins here. Sooho has dealt with a lot of ghosts in his life, but he’s never had to deal with an angel like Taker before. How will Sooho take responsibility to break Taker’s wing?
