From Renta!

I'm Yuzu Hayami, a college student who lives on his own. Today, I had a hectic day at my part-time job and had to do a bunch of overtime, and then on my way home, I hurt my ankle, got mugged while I was passed out, and had this drunk old man try to have his way with me because he thought I was turning tricks…
This guy who was walking by saves me, but it turns out he's a club host, the likes of which I despise…
Since I couldn't walk well due to my injury (it's light, though), I asked him to help me back to my apartment, but… huh? A vacant lot? …Why?
What happened to my apartment!?
