After his happy-go-lucky lovestruck parents suddenly decide to go on an amorous traveling adventure, Yuki is shuffled off to live with one of his dad's old friends. He knows very little about his new living circumstances, save that his dad's friend is an author with three children.

Something seems a little off about the girl who's sent to meet him, the fidgety and overly anxious Aya, but he doesn't fully understand what's going on until he arrives at the house. Yuki, who has had very little to do with women thus far in his life, is now set to live in a house with four of them. The head of the house is actually an author of erotic novels, and she habitually forces her three daughters into embarrassing sexual situations. How will Yuki cope with his new life?

I think the scary protagonist and weird family dynamic has been explored in other manga already, and much better. I read this up to chapter 7 a while ago, and read up to chapter 12, but not much has changed to shake my opinion. This manga is average at best.

The Art is only little above average.
Plot: well it's only a collection of short stories, there is no plot. OK, there is some beginning romance between the two teenagers, but is this a plot? Slice-of-live at best.
It shall be a comedy, but the jokes are forced ones. And i get bored, i mean really bored, of the nose-bleeding of the main character because he see or remember(!) something connected to sex, even in the remotest way . In some chapters he bleeds into unconsciousness. He get aroused even by 10 years old girl and nosebleeds into unconsciousness, is he lolicon or what?
Yeh, yeh, for some teenager witch sees this nosebleeding orgy for the first time it is funny, i think this is boring.
Some nice fanservice. A lot of ecchi stuf. Nice start setting for the story, which is consequently draw down into ecchi hell in which every character traits ceased to exist before they have a chance to exist first place. Thats all what this manga is about.

I would like to see a good ecchi comedy, but well, i have to search a little longer. I have stopped reading this manga. I recommend for others to search for some thing better to read.

Well it started of good, but then there is no progression whatsoever from male lead. It is just frustrating, i don't even get it why is he still a virgin and too easily agitated by women when he lives in that kind of environment... He is not male if you ask me...

Is he gay

He must be gay because no red blooded straight highschool male would see this situation as anything other than heven. He is living in an erotic dream and only wants to escape. What a moron! Another prime example why japan has a declining birthrate.
