Story (4/10):

It's about a kid who loves his older sister to the point where they enter a forbidden relationship with her, but for some reasons, there are other girls who almost use him for his penis. Which totally feels out of place when it comes to the manga.

Art (6/10):

It's an old-style art from 2008. It's neither good nor bad. It's decent.

Characters (6/10):

Sora's character is the classic boy who always gets played with, but aside from that he's really good at helping others and is quite caring. Aki is has that older sister/motherly care aura around her when it comes to Sora, but in school, she is the usual top student who's good at everything. As for the twin sister Nami, I didn't really like her. She wants things but doesn't try to get them and does unnecessary things that won't benefit her from achieving her dreams. Overall, the cast feels like the usual, the only character I liked in the manga is Runa, because of her personality.

Enjoyment (4/10):

I would say that I enjoyed the first 20 chapters because it felt like a guilty pleasure, but by the end, I didn't really enjoy it because the point where it ended felt out of place and there should've been more to it. It left a bad after taste after finishing it.

Overall (5/10):

It was really enjoyable at first, but by the end, I knew that the decision made was for the best, but I still felt like the ending needed a little more context than what it did.
I wouldn't recommend it to anybody unless they are into incest/love-between-siblings/ecchi then that would be a good recommendation for them.
