There are people that will hate this series by default because they don't agree with the brother-sister genre entirely but I have to say this manga does an amazing job showing everything the genre has to offer. The point isn't that she's his sister, the point is that she is the closest person in the world to him. He falls in love with her because they share all the same interests and look out for each other and because he can't imagine being with anyone else.

It isn't something you have to want a relationship with your own sister to enjoy, it is simply a love story between two incredibly close people and the whole forbidden aspect of the relationship just adds some tension to spice things up.

The important thing to remember is that fantasy is by definition not reality and the inability to distinguish between the two means you are literally insane. So if you can't enjoy a heartfelt story about two people that fall in love and have to sneak around because you are projecting yourself and your own sister onto them then you actually have a mental problem. If you dislike this story because of the characters themselves and not the genre that is fine but I'm sick of people having an instant "oh that makes me want to puke" reaction to everything that comes out of a specific genre because they want to show off what a mature and healthy person they are (that can't differentiate a fictional manga from reality).

Anyways onto the story itself: I don't want to spoil anything so I won't touch on specifics but it is full of moments that made me laugh, warmed my heart, and was just a fantastic read so far. I'm a sucker for love stories but this is one of the best I've seen. Also unlike a hundred billion other romance series this relationship actually has seen some progress in the 17 chapters that are currently available so it doesn't look like a complete waste of time for readers that might want to pick it up and see something actually progress and not just the same recycled jokes for hundreds of chapters.
