Tsubasa Hachino attends the same university and lives in the same apartment building as I do. After becoming friends with this otaku girl over our shared love of manga... an unexpected development was waiting for me!

I can do whatever I want with her, like she's a beast in heat! I was over the moon, but I had made a huge mistake...
