For a certain reason, you is currently in need of money. They were searching for some way to get it.

One day, you finds a well-paying part-time job. The job is simply cleaning a room for 5,000 yen an hour. It's a little suspicious, but desperate times call for desperate measures.

Upon contacting the employer immediately, they got an instant OK. It's getting more and more suspicious, but they can't really back out now.

Apparently, they want the cleaning done right away, so you is to start work tomorrow. No specific time was given. The sooner the better, but they said they're always there. What an overly casual employer.
