My Cool and Straightforward Girlfriend Won’t Let Me Sleep Today Either

“I won’t let you sleep tonight.”

I, a humble university student, started living alone due to family circumstances. My girlfriend, Natsuki, often comes over to my room. We’ve been dating for four years now.

Our relationship is no longer in its infancy, it’s become something we’re entirely accustomed to.

However, as we’ve grown older, we’ve overcome various “obstacles”. As a result, my somewhat cool and straightforward girlfriend…

“Tonight, I won’t let you sleep until morning.”

…has transformed into a rather naughty woman who frequently attacks me. The mundane daily life with her, now in its 4th year, has become enjoyable in its chaos.

But, you know, it’s getting really tiring. Can someone please help me…?
