Second-year middle schooler Nao Takanashi loves her older brother Shuusuke to the point where she has developed a brother complex. Wanting her brother to see her as a woman, Nao makes advances toward him on a daily basis, which often results in Shuusuke succumbing to and encouraging more of her teasing.

One day, while throwing away porn magazines from her brother's room, Nao finds an album containing his childhood photos—none of which include her. Having discovered the truth behind her family relationships, Nao becomes ever more affectionate toward Shuusuke. However, it does not take long for her dreams of monopolizing her brother to be put in jeopardy.

The first thing that one is going to notice is just how completely ugly ...

Light spoilers.

I honestly don't think this anime was too bad. I mean, why would you watch this show if you had something against incest? I don't like it in real life, but in anime it's okay, imo. But it states in the first episode that they aren't blood-related, and that the sister was adopted.

The story wasn't anything new. A girl's crushing on her step-brother, he has a childhood lover who wants him, and some cute girl also likes him (and at the end a cosplay-obsessed girl tries to steal his heart). I find this on the unrealistic side of things because he's commonly referred ...

A few weeks ago, I asked my friend what the worst manga he had ever read was. He answered without hesitation that it was a manga called "I don't like you at all big brother!". I decided to research this title and discovered to my utter terror that this manga actually was popular enough to receive a 13 episode anime adaptation. I watched this anime on my laptop during a 5 hour car trip. I weep ...
