Soobin is an ordinary student in high school who is bullied. One day he confessed his love to a popular girl and after that they started bullying him. Because of the bullying, he became humble and silent, as well as very timid.. One day, when he was walking home after another bullying at school, he heard a muffled thump in the bushes. When he looked in there, he saw a thin, short girl with blonde hair gathered in two cute pigtails.. She was wearing a white dress and barefoot.. She was scratched and bruised. He could also see the small white wings behind her back.. One of her wings was broken.. Is it really an angel?..
