Shunrai to Noise

Suzu keeps a low profile at school to avoid being associated with her flashy, popular older brother. Once word gets out that she is his sister, her quiet routine collapses as the in-crowd swarms her, flattering her in hopes of getting closer to him, and a delinquent with a grudge against her brother attacks her. Her rescuer is Hata, one of her brother's friends and exactly the sort of person she has been avoiding, yet his pushy kindness slowly draws her out and gives her a life of her own.
