This story is a love story between an older sister and her younger brother, who are not related by blood. This story contains 80% romance and 20% ecchi, so it is best to read this story as a pe*verted love story and not perversion with a little bit romance.

For me, the story is good. It's reasonable (since I also read the stepbrother's diary, I found this story more lovable). Although if you don't read the stepbrother's diary version, I think you'll wonder like "what does this boy thinks?"

Spoiler

even though there're actual dialogue hints that he love her sister in a romantic way, and will be slightly opened when he confessed.

the romance is more dominant than the smut. It's not a harem either. From total 22 chapters, I think there're only 30% filled with adult scenes, otherwise it's their "daily life". What make me love this series more is the comedy, it's funny and enjoyable since I'm a comedy-lover.

however, there are some parts that left undescribed.

Spoiler

1). The parents never know about it until the end of the series, even though I was expecting what whould happens if they know.

2). This one maybe just my own personal wish, but I want to know what will happen to Amane after the last scene where Soutarou take her away in front of her ex.

I love Soutarou though, even though his thoughts are pretty wicked, overall, he's a nice boy. <<less
