From MangaHelpers:

Ten years ago, Nanase Kouhei was the top host of the Roppongi district of Tokyo. He gave that life up, though, to become a husband, father, and company man. Now, he has a beautiful wife, Momoko, and a little daughter, Orie, who will be going to school in a few years. They also just bought an apartment and have a large long-term loan to pay off for it.

Then one unfortunate day, Kouhei is laid off from his job. Now he faces the terrifying prospect of caring for his family, when he has no guarantee of finding a decent new job. It's enough to make Kouhei quietly turn back to his previously successful career as a Roppongi district host, and he returns to his old club "Rink." But can a 31-year-old man really make a comeback in such a young man's industry? [tethysdust]
