Tobioriru Chokuzen no Doukyuusei ni "Sekkusu Shiyou!" to Teianshite Mita.

My first love, Koga Kurumi. Her beauty and personality, which are beyond what you'd expect from a high school student, invite jealousy, isolate her, and - she was on the verge of jumping off the roof due to bullying. So, what can I do...? "Let's have sex!" I'll scream out my love to the death and make a place for you in this world!
