Sayu Takada never really had any friends seeing as which she always held an unwelcoming environment around her. Rin Kagami saw past her barrier though and he's the only one to see her soft and friendly side. He secretly has a crush on her, but it doesn't seem like it's going to go far when the popular boy Sukkah Tsukiha likes her too. Not just likes her, but is obsessed with her. Stalking her every time she goes home and staring her down in class. Sayu doesn't notice that Sukkah has a strange obsession for her. Instead Rin does and he's not so happy about it either...
