Suiren Graffiti (Light Novel)

Nice to meet you! My name is Ikeno Suika. I’ll be starting high school this spring. As Mom is working, the task of looking after my younger brother and sister falls upon me. Right now, what most occupies my mind is the girl who sits next to me, Niwagami Ren. She is feared in the class as a delinquent, but I do not feel that to be the case somehow… However, one day I accidentally found out about her secret, and ended up staying together with her?!
