Namete, Kajitte, Tokidoki Medete

I'm Haru. first year in high school. Please listen to my troubles. I accidentally gave my love letter to the number one problem child at school, Seishirou-lun... Even though I told him to give it back, he won't. He says I'm already his girlfriend...He'll chase me down if he sees me at school, he takes my lunch, keeps his eye on me, and e-even kisses me...Ah and doing perverted stuff...!! And he's also living at my place.... I'm definitely not his girlfriend, so please let me go already!!!
