He worked so hard to be hired in his job. Spent days and nights of preparing for interview, reviewing for exams, and finally get his first job. It's not easy as he expected working for a government institution. Of course, the salary is great, and the job is not really tiring.
He has to fight against his conscience. Got the job cleanly. Never used anyone to be hired. His supposed next goal is to get promoted. But those in a higher position, the seniors, asks him to do something. That's giving his signature on some fake projects, as well as genuine projects but with fake costs. He was also promised to get some kickbacks.
He is voiceless. Exposing the corruption may risk his or even his family's lives. Rather, he decided to resign from his job to protect his conscience from getting involved in the corruption.
