Bones of Steel.

Heita Tomishima is a very conscientious but awkward young man at a mid-sized construction company. He loves working on-site, but one day is suddenly transferred to Operations, a unit whose work is totally outside his comfort zone. Its remit is to land major projects, including public works, and in-house it's cynically known as the Bid Rigging Department. Working under a crusty-old director, a crass macho type, a go-getter doyenne, and a cunning manager adept at hiding his true intentions, Heita dedicates himself to winning a public works contract worth billions.
