Aki lives a wonderful life. She's got the beauty, intelligence, sports skills and popularity. Although, that changes when she's at home. She's very lazy and untidy leading her little brother, Sora, to clean it. Plus, Sora's twin sister Nami, is madly inlove with her best friend Kana, but doesn't admit it.

Bullied by Nami and often teased by Aki, Sora is left to do chores their mom has to do. But, where's their mom? She's busy with work like most moms. I'll add more, Sora actually harbors lustful feelings for his big sister Aki, who feels the same. It's an adventure and they have to work hard in order to keep these feelings from being discovered by their parents.

OKAY STOP. Let's take a break here and read my opinion. I saw this manga when I was looking for something ecchi-ish to read, but I didn't think it was this strong. Sex is shown throughout the whole story, but no showing of genitals to be safe.

The story is about two siblings having deep love for each other to the point that they actually committed incest. But doing it once didn't satisfy them, as they did it many more times and stopped when they were caught by somebody they know. I'll be hiding that character for now and will reveal it later.

The story progresses as Sora makes more friends, girls to be exact, and these girls have the same feelings Aki has for him. At volume two, the mother they see is actually their aunt, who acted like their mother when they were kids. The twins do not know what's going on, but Aki does, as she was the one who told their aunt not to reveal it. If she were to, the kids would be devastated due to the fact that their real mother died in a car crash and Aki and their aunt were lying. At the end of volume two, Nami and Sora engaged in sex. Well, not really engage but more of "Nami raped Sora." because she was jealous that Sora and Kana were actually progressing more that they were.

Volume three and four are just fillers in my opinion, just sex here for Sora and sex there. But, there was a point that when Sora took Kana's virginity, they were secretly filmed by the jealous Nami. At volume five, Sora and Kana were chosen to become the models of a photo-shoot. Then Sora befriends more minor characters and had sex with them. When volume five reaches the end, Kana had discovered Sora and Nami having sex and joins them, competing with Nami. The prize? Sora. Why does the little fucker have all the fucking girls?! I feel lonely. (┳Д┳)

One of those threesomes actually fixed Nami and Kana's relationship. They forgive and reveal their feelings towards another. At the final volume, there's a man who comes in to their house and Aki calls him father. But, Nami and Sora did not acknowledge him as he wasn't there during their childhood days. In one of those chapters, Aki becomes aroused and she and Sora again have sex again in the living room. Believing that the door was locked and nobody else was in the house, they continued. They actually finished and Aki says she's thirsty, leading Sora to get her a glass of water, but was stopped as they see their father standing by the door and was watching them the whole time.

This leads to Aki being taken away by their father and goes off somewhere far. Sora becomes lonely and acts strangely for some time, but gets the words of encouragement and goes off, searching and wanting to meet his beloved sister. He finally reaches his destination despite being in the road for days. As he meets Aki, they go to the hospital and Sora sees that his "father" was in it. Their father had been suffering. He still becomes stiff and refuses to call him father, leading to Aki slapping him really hard.

Eventually, their father dies and the whole family attends the funeral. It's revealed that the reason their father had separated them was because he committed incest too, and they were the product. It comes down to the point that Sora had to make his decision. Aki stays, or not. As he thinks hard, he does not notice the train leaving, with Aki. His final words on that chapter was "Don't go."

In the end, Sora is shown putting flowers on their mother's grave. That means he already knows the truth. He starts praying but a shadow catches his attention. He stands up and talks about their mom and dad finally being together again and will never be separated. It turns out that it was Aki, who arrived. In the end, nothing could stop their love for each other and they continued seeing each other.

The characters filled their roles nicely although there were characters who only appeared in filler chapters. A minus one for that.

Love, as portrayed in this manga, moves me. I don't care if you call me a pervert for the ecchi things in this manga. What I'm after is the story. Classic and simple. Forbidden Love. It's the main point of the manga. How will the lovers survive? How will their friends react? How long will they be able to keep this up? How will the society accept them? These are the questions that lingered in my mind while reading it.
