Ie ni Kaeru to Kanojo ga Kanarazu Nanika Shiteimasu (Light Novel)

I am a proud loner who extols the perks of living alone. But one day, an unfamiliar girl, Akari barges into my house. She was here as a “rental family” and even transferred to my highschool, spelling the start of our secretive cohabitation, but. “Eh? It’s not like I’ve done anything, okay?” Despite putting on the airs of an honor student in school, at home, she trespassed into the shower when I was bathing in nothing but a towel, and is also the owner of unspeakable hobbies. To make things worse, our situation was exposed to my classmates, causing my ideal loner life to gradually crumble into pieces. Just let me off already, seriously… What is going to happen to my life?
