Roommate Corruption is a story about a guy who's about to go to university.
He left his hometown and is now looking for a place to live for a couple of weeks,
until he finds a suitable flat and finishes his enrollment. Gladly,
his childhood friend named Hana lives near the university, and she lets our hero live in her apartment for a while.

But as soon as our hero moves in, he finds that she changed a lot - she's arrogant, doesn't take him seriously and just seems like a total bitch. But our hero knows how to change that, and he quickly starts educating her...
