The story is great, really great, the plot is nothing new, characters with common traits, even the main one. But what separate it is the style and how the story progresses. It's a 4/5 for me, just don't have that originality for the 5.

Don't usually do reviews, but this story is great.

It's about a normal guy who has to choose between his siblings, thereby deciding who will become his real little sister. That little sister will be given some of the inheritance that the guys rich family member left behind and pretty much be set up for life, whereas the other little sisters will be on their own.

Throughout the novel he begins to understand each of the little sisters more and more, until he eventually makes his decision. There's drama, conflict, love and... more>> the occasional comedy, it's well worth a read. <<less

Refreshing read, tho probably axed. TL is kinda questionable but still good. You can expect all the things that make a title like this appealing, and the fact that it has an ending is a plus.

Like the previous guy said, this is not another siscon love comedy. Don't let the romance tag fool you, this story is about a guy who has to choose who to make his little sister. They don't fall in love with him and want to marry him, they fall in love with him and want to make him their older brother. There's no "I want to be more than family/little sister " stuff in this story. They learn to get along with each other as family, no s*upid catfights over... more>> onii-chan, they get along properly. <<less

Honestly it was extremely good. Very very refreshing story.

I wasn't expecting much. Thought it was just another siscon love comedy. But wrong. Totally wrong.

First of all, it's not siscon. There are some parts with brocon, but there is no romantic relationship between siblings in the end.

Anyway, I liked reading it. There were some funny parts, some cute parts, and some frustrating parts. I gave it 4 stars because some parts really dragged, and I struggled to continue. Also, because some of the characters really pissed me off and were just forgiven.




Overall, though, I recommend it!
