Hyori is a 15 year old high school student with a cold facade. She looks cold-hearted and emotionless, but she is actually very cheerful, nice, and thoughful, which is exactally why she has been living in an abandoned park for the last 2 weeks, because she doesn't want to bother anybody. She has a brother but she rarely sees him and he changed his phone number without telling her. She doesn't want her friends worrying about her either. So, what will happen when she has a fever after being beat up?
