(y/n) was no ordinary human. He was a human who is basically the ultimate master at accounting at a young age. He is also a serious workaholic because of his disability(s) or how his brain worked. After he graduated with a master's degree and got the major accounting certifications. One day, he found out about someone needing to hire a new accountant. (y/n) never expected to meet Lucifer herself and get a job in hell. However, he gets paid very high because all of the licenses about accounting he has and how many hours he can work. This is life as a master accountant working for hell and with demons. What will that life be like?
