My Wife Died in an Accident After I Won the Lottery

Gu Nian exchanged a lottery ticket for a chance to go home, only to unexpectedly learn that his wife had fallen to her death at a construction site. Three months later, someone came knocking. His lover claimed to genuinely want to know the true cause of his wife's death, but again and again, he used his guesses to expose my lies and force me to tell the truth. In the end, I resigned myself to revealing everything. On the day I was sent to prison, however, I produced a certificate diagnosing me with a mental illness and overturned his theory.
