This takes place In Korea. You are in high school, you are an antisocial person who is awkward and nervous to attention. But one day you accidentally caught the attention to a quiet popular upperclassman that is very handsome that girls around the school are inlove with him. It all started when you fell during a running test in pe and you had a bleeding nose. After seeing you from his classroom window, you weirdly remind him of a puppy getting kicked. And the rest is history after.
