[MASM-028] The gal who lives next door has been hanging around my house without permission and is acting all arrogant, so I thought I'd teach her a lesson, but she turned out to be a crazy sex monster and I ended up getting taught a lesson instead. Rin (Censored)

I got home early for the first time in a while, so I thought I'd watch some anime that's piled up. When I got home, I found a gal lying on my bed reading a manga. That's right... I'd forgotten about her... This gal is Rina-chan, the daughter of Takase-san, who lives next door. She doesn't get along with her parents, so she doesn't want to go home as much as possible, and she just stays in my room all the time. I've warned her many times not to get on the bed in her uniform, but she doesn't listen at all, saying things like "You're happy about it though lol". I'm so angry! I'm going to show her what happens when a high school girl sneaks into a man living alone's room! (※This is a story about a man being taught a lesson)
