Sakura, my childhood friend who lives next door, is a typical spinster. And a NEET. Habitat: My room. Equipment: The same shirt I've worn for 10 years. Occupation: Home security. It had become my daily routine to check on Sakura's survival and get her food. But then, I finally got my first girlfriend! ...But (tears) Sakura suddenly changed and started attacking me! "Stop it! I've got a girlfriend!" My resistance was futile, but even though I'd only just gotten a girlfriend, I was united with Sakura. It's crazy! It feels too good! I love her, but we're just too compatible and I can't stop! My feelings of guilt towards her are growing, but at the same time, the number of used condoms continues to grow!
