This show's got p****. And lots of it. So I might as well warn you that if you're a woman you'll definitely hate it. And if you're a woman from some third-world country that's plagued with oversexed media and the drooling goons that go with it, then you need to find another hobby.
This show has the same characters and uses the same theme. But it's obviously three different paths based on three different women. (Probably a thumbs up to some game it originated from.) Here we have Jun; a guy who lost his wife in an accident and ends up doing his own sister-in-law. Meanwhile his father wants him to take over the Hungry Bear diner using the "Malcolm X plan" ("by any means necessary"). So he manages to get his thing on with three more women who just happen to work at the Hungry Bear with him. Sometimes he lets two or three goons who frequent the diner join in. Sometimes he doesn't.
The art and animation of the show reminds me of SoulTaker. The sex can get low and depraved at times, but you get to see a lot of marital arts; a lot of action that replaces kung-fu with sex. It also helps that it's nicely done as a restaurant theme.
Anime 18 has been known to release hentai anime so vile and disgusting that even their logo makes you cringe more than Manga Entertainment's other logo (of that toothy bald-head guy). In fact, that show was so evil that that my DVD player wouldn't view it at first.
