A man who lives for his job. Dedicated to the point of obsession, Lei is a law-abiding and gifted cop. Lei is a workaholic, who becomes fixated on his cases and on tenaciously seeing them through to the end at all costs.

Despite this, Lei's solution has always been to throw himself back into his work.
